Vulnerability with high CVSS value discovered
A vulnerability with a particularly high CVSS (Common Vulnerability Scoring System) score of 9.8 affects several Fortinet products and allows unauthenticated attackers to execute arbitrary code or commands, Censys announced.
Up to 2,878 instances worldwide could potentially be affected, says Censys, a provider of threat hunting and attack surface management tools. This could happen by attackers sending HTTP requests with specially crafted hash cookies. According to Censys, the stack-based buffer overflow vulnerability affects FortiVoice, FortiMail, FortiNDR, FortiRecorder and FortiCamera.
The manufacturer published a security advisory last week summarizing suspicious log entries, IP addresses, modified system files and changes to configurations. It is recommended to search for signs of compromise using the CLI commands provided and to examine certain system files. In addition, HTTP/HTTPS management interfaces of affected devices should be disabled until the patches are installed. Patches are available for the affected products. There is currently no indication that a public proof-of-concept exploit exists.
In an investigation of threat intelligence data, Censys observed that a total of 2,878 Fortinet devices worldwide are potentially vulnerable to the exploit. As no information on the specific versions was available during the investigation, not all observed instances are necessarily vulnerable. In addition to numerous instances in the USA, some systems in Europe and Germany are also potentially affected. The results on the distribution of potentially affected instances were determined using the tools of the Censys platform.
