Fortinet has issued a critical patch for a severe SQL injection vulnerability affecting its FortiWeb product. Identified as CVE-2025-25257, the flaw resides within the Fabric Connector feature. This vulnerability allows an unauthenticated attacker to execute arbitrary commands and potentially gain access to sensitive information on affected systems. The issue stems from improper input sanitization, enabling attackers to manipulate SQL queries through specially crafted HTTP requests. The vulnerability has a high severity score of 9.8 out of 10, highlighting the significant risk it poses to organizations.
The vulnerability specifically impacts multiple versions of FortiWeb, including versions 7.6.0 through 7.6.3, 7.4.0 through 7.4.7, 7.2.0 through 7.2.10, and 7.0.0 through 7.0.10. The FortiWeb Fabric Connector acts as a crucial middleware, connecting FortiWeb web application firewalls with other Fortinet products for dynamic security updates. Attackers can exploit this flaw by sending malicious SQL payloads within HTTP Authorization headers, bypassing authentication controls and potentially leading to remote code execution. Researchers have demonstrated that this SQL injection can be escalated to achieve full system compromise by leveraging MySQL's INTO OUTFILE statement to write files to the server and executing them via Python scripts. Given the critical nature of this vulnerability and the availability of proof-of-concept exploits, Fortinet strongly urges all users of affected FortiWeb versions to apply the provided patches immediately. Organizations should update to FortiWeb 7.6.4, 7.4.8, 7.2.11, 7.0.11, or later versions to mitigate the risk of exploitation. As a temporary workaround, disabling the HTTP/HTTPS administrative interface can also help reduce exposure until the patches can be applied. Swift action is crucial to prevent potential data breaches and unauthorized access to sensitive systems. Recommended read:

Iranian advanced persistent threat (APT) groups have significantly escalated their cyberattacks against critical U.S. infrastructure, with a notable 133% surge in activity observed during May and June 2025. The transportation and manufacturing sectors have been identified as the primary targets of these intensified operations. This trend aligns with ongoing geopolitical tensions, as well as recent warnings issued by U.S. authorities like CISA and the Department of Homeland Security, which highlighted U.S. entities as prime targets for Iranian cyber actors.
Nozomi Networks Labs reported a total of 28 distinct cyber incidents linked to Iranian APTs during May and June, a substantial increase from the 12 incidents recorded in the preceding two months. Among the most active groups identified are MuddyWater, which targeted at least five U.S. companies primarily in the transportation and manufacturing sectors, and APT33, responsible for attacks on at least three U.S. entities. Other groups such as OilRig, CyberAv3ngers, Fox Kitten, and Homeland Justice were also observed conducting attacks against U.S. companies in these critical industries. The resurfacing of the Iranian-backed Pay2Key ransomware, now operating as Pay2Key.I2P, further highlights the evolving threat landscape. This ransomware-as-a-service operation, linked to the Fox Kitten APT group, is reportedly offering an 80% profit share to affiliates targeting Iran's adversaries, including the U.S. and Israel. This financially motivated scheme has also demonstrated an ideological commitment, with claims of over 51 successful ransom payouts, netting substantial profits. The use of the Invisible Internet Project (I2P) for its infrastructure represents a notable shift in RaaS operations, potentially enhancing its evasiveness. Recommended read:

A Türkiye-linked hacking group, tracked by Microsoft as Marbled Dust, has been exploiting a zero-day vulnerability, CVE-2025-27920, in the Output Messenger application since April 2024. This espionage campaign has targeted Kurdish military personnel operating in Iraq, resulting in the collection of related user data. The vulnerability impacts Output Messenger version 2.0.62 and involves a directory traversal flaw that allows remote attackers to access and execute arbitrary files. A fix was released by the developer, Srimax, in late December 2024 with version 2.0.63.
The attack chain commences with the threat actor gaining authenticated access to Output Messenger's Server Manager. It is suspected that Marbled Dust uses techniques like DNS hijacking or typosquatted domains to intercept the credentials required for authentication. This access is then abused to collect user credentials and exploit CVE-2025-27920 to drop malicious payloads. These payloads include scripts like "OM.vbs" and "OMServerService.vbs" into the server's startup folder, and an executable "OMServerService.exe" into the server's "Users/public/videos" directory. The final stage involves the execution of a multi-stage backdoor deployment. The "OMServerService.vbs" script is used to invoke "OM.vbs" and "OMServerService.exe." The latter is a Golang backdoor that connects to a hard-coded domain, "api.wordinfos[.]com," for data exfiltration. On the client side, the installer extracts and executes both the legitimate OutputMessenger.exe file and OMClientService.exe, another Golang backdoor. This client-side backdoor also connects to a Marbled Dust command-and-control (C2) domain, enabling further malicious activities. Recommended read:

Fortinet's FortiGuard Labs has revealed a multi-year, state-sponsored cyber intrusion targeting critical infrastructure in the Middle East. The intrusion, attributed to an Iranian APT group likely Lemon Sandstorm, began as early as May 2023, with potential traces back to May 2021, and went undetected for nearly two years. Attackers gained initial access through compromised VPN credentials, deploying multiple web shells and custom backdoors throughout the infrastructure.
This Iranian APT exhibited significant operational discipline, constantly rotating tools, infrastructure, and access methods to maintain their foothold. After gaining access, they installed backdoors such as HanifNet, HXLibrary, and NeoExpressRAT. The attackers used in-memory loaders for Havoc and SystemBC to avoid detection, plus custom loaders to execute malware directly in memory, avoiding disk-based detection. Throughout the campaign, FortiGuard Labs identified at least five novel malware families, including HanifNet, NeoExpressRAT, HXLibrary, RemoteInjector, and CredInterceptor. The attackers also modified legitimate OWA JavaScript files to silently siphon credentials, disguising malicious scripts as legitimate traffic. The attackers used open-source proxy tools such as plink, Ngrok, Glider Proxy, and ReverseSocks5 to circumvent network segmentation. Recommended read:

Multiple security vulnerabilities are currently being exploited in Fortinet and SonicWall products, posing a significant risk to organizations using these devices. The Cybersecurity and Infrastructure Security Agency (CISA) has taken notice, adding the SonicWall SMA100 Appliance flaw (CVE-2021-20035) to its Known Exploited Vulnerabilities catalog, urging federal agencies to apply mitigations by May 7, 2025. This vulnerability, which impacts SonicWall SMA 200, SMA 210, SMA 400, SMA 410, and SMA 500v devices, allows remote authenticated attackers to inject arbitrary operating system commands.
Attackers have been actively exploiting the SonicWall SMA100 vulnerability (CVE-2021-20035) since January 2025. SonicWall has updated its security advisory to reflect the current active exploitation of the flaw which can lead to code execution, as opposed to a denial-of-service. While the vulnerability affects SMA100 devices running older firmware, customers are urged to upgrade to the latest firmware. In addition to the SonicWall vulnerability, threat actors are employing new techniques to exploit a 2023 FortiOS flaw (CVE-2023-27997). This involves manipulating symbolic links during the device’s boot process, allowing attackers with prior access to maintain control even after firmware updates. Fortinet has released security updates for FortiOS and FortiGate. Organizations using Fortinet products should apply the latest patches. Similarly, SonicWall users are advised to upgrade to the fixed versions of firmware, specifically 10.2.1.1-19sv and higher, 10.2.0.8-37sv and higher, or 9.0.0.11-31sv and higher. With both SonicWall and CISA confirming the CVE-2021-20035 exploit, details about the attacks remain scarce. Recommended read:

A significant cybersecurity incident has come to light involving Fortinet devices. Reports indicate that over 16,000 internet-exposed Fortinet devices have been compromised using a symlink backdoor. This backdoor grants attackers read-only access to sensitive files, even after security patches are applied. The Shadowserver Foundation, a threat monitoring platform, has been tracking the situation and has reported the growing number of affected devices. This active exploitation underscores the critical need for organizations to implement security updates promptly and rigorously monitor their systems for any signs of suspicious activity.
Fortinet has acknowledged the attacks and has taken steps to address the issue. The company has released multiple updates across various FortiOS versions, including versions 7.6.2, 7.4.7, 7.2.11, 7.0.17, and 6.4.16. These updates not only remove the established backdoor but also modify the SSL-VPN interface to prevent similar occurrences in the future. Furthermore, Fortinet has launched an internal investigation and is collaborating with third-party experts to fully understand and mitigate the scope of the breach. An AV/IPS signature has also been developed to automatically detect and remove the malicious symlink. Concerns about espionage have also arisen after the exposure of a KeyPlug server. This server exposed Fortinet exploits and webshell activity, specifically targeting a major Japanese company, Shiseido. A recently exposed directory on infrastructure tied to KeyPlug malware revealed tooling likely used in active operations. The server was observed to be live for less than a day, highlighting the need for organizations to monitor for short-lived operational infrastructure. This discovery reveals the potential for advanced adversaries to maintain persistent access through sophisticated methods, making detection and remediation increasingly challenging. Recommended read:

Fortinet has issued critical fixes following the discovery of a new method employed by cyber attackers to maintain access to FortiGate devices, even after patches were applied. The attackers are exploiting vulnerabilities such as FG-IR-22-398, FG-IR-23-097, and FG-IR-24-015, creating a symlink that connects the user filesystem to the root filesystem within a folder used for SSL-VPN language files. This allows attackers to quietly read configuration files without triggering standard detection mechanisms. If SSL-VPN has never been enabled on a device, it is not affected by this vulnerability.
Fortinet has responded by launching an internal investigation, coordinating with third-party experts, and developing an AV/IPS signature to automatically detect and remove the symbolic link. Multiple updates have been released across different FortiOS versions, including 7.6.2, 7.4.7, 7.2.11, 7.0.17, and 6.4.16. These updates not only remove the backdoor but also modify the SSL-VPN interface to prevent future occurrences. Customers are strongly advised to update their instances to these FortiOS versions, review device configurations, and treat all configurations as potentially compromised, taking appropriate recovery steps. The Shadowserver Foundation reports that over 16,000 internet-exposed Fortinet devices have been compromised with this new symlink backdoor. This backdoor grants read-only access to sensitive files on previously compromised devices. CISA has also issued an advisory urging users to reset exposed credentials and consider disabling SSL-VPN functionality until patches can be applied. This incident underscores a worrying trend where attackers are designing backdoors to survive even updates and factory resets, highlighting the need for organizations to prioritize rapid patching and proactive security measures.

Over 16,000 Fortinet devices have been compromised due to a novel symlink backdoor, allowing attackers to maintain read-only access to sensitive files. This was reported by The Shadowserver Foundation. The attackers are exploiting known vulnerabilities in FortiGate devices, specifically targeting the SSL-VPN language file directory. By creating a symbolic link between the user filesystem and the root filesystem, attackers can bypass security measures and access critical files even after patches are applied.
Researchers observed that threat actors are leveraging a new method to exploit previously patched vulnerabilities in Fortinet's FortiOS, specifically targeting FortiGate VPN appliances. The original flaw, CVE-2023-27997, had a fix issued, but threat actors can still gain access by manipulating symbolic links during the device's boot process. This enables threat actors with prior access to maintain control over the device, even after firmware updates. The issue stems from how FortiOS handles file permissions and symlinks when restarting, allowing malicious files to persist and re-enable vulnerabilities that were supposedly fixed. Fortinet has responded by releasing several updates and new security measures to block further attacks. These measures include launching an internal investigation, coordinating with third-party experts, and developing an AV/IPS signature to detect and remove the symbolic link automatically. Multiple updates have been issued across different FortiOS versions, including 7.6.2, 7.4.7, 7.2.11, 7.0.17, and 6.4.16. These updates not only remove the backdoor but also modify the SSL-VPN interface to prevent future occurrences. Organizations are urged to upgrade to the latest secure versions to mitigate the risk.
