CVE-2025-32756
A stack-based buffer overflow vulnerability [CWE-121] vulnerability in Fortinet FortiCamera 2.1.0 through 2.1.3, FortiCamera 2.0 all versions, FortiCamera 1.1 all versions, FortiMail 7.6.0 through ...
Affects 6 products across 1 vendor.
Buffer overflow corrupting the program stack, typically overwriting the return address for code execution.
Software writes data past buffer boundaries, corrupting memory and potentially enabling code execution.
A critical stack-based buffer overflow vulnerability exists in multiple Fortinet products, including FortiCamera, FortiMail, FortiNDR, FortiRecorder, and FortiVoice. This vulnerability allows a remote unauthenticated attacker to execute arbitrary code or commands by sending specially crafted HTTP requests with a malicious hash cookie. The affected products span several versions, and the vulnerability has a CVSS score of 9.8, indicating a high severity. Immediate action is required to mitigate the risk of exploitation.
BSID: BS-2025-GLOBAL-269843-C • Model: Qwen/Qwen2.5-72B-Instruct-AWQ • Confidence: HIGH

A stack-based buffer overflow vulnerability [CWE-121] vulnerability in Fortinet FortiCamera 2.1.0 through 2.1.3, FortiCamera 2.0 all versions, FortiCamera 1.1 all versions, FortiMail 7.6.0 through 7.6.2, FortiMail 7.4.0 through 7.4.4, FortiMail 7.2.0 through 7.2.7, FortiMail 7.0.0 through 7.0.8, FortiNDR 7.6.0, FortiNDR 7.4.0 through 7.4.7, FortiNDR 7.2.0 through 7.2.4, FortiNDR 7.0.0 through 7.0.6, FortiRecorder 7.2.0 through 7.2.3, FortiRecorder 7.0.0 through 7.0.5, FortiRecorder 6.4.0 through 6.4.5, FortiVoice 7.2.0, FortiVoice 7.0.0 through 7.0.6, FortiVoice 6.4.0 through 6.4.10 allows a remote unauthenticated attacker to execute arbitrary code or commands via sending HTTP requests with specially crafted hash cookie.
Source: NIST NVD / MITRE CVE Database
The vulnerability can be exploited remotely without authentication. An attacker can send a specially crafted HTTP request with a malicious hash cookie to trigger a stack-based buffer overflow, leading to potential remote code execution. The attack vector is network-based, and the attacker does not require any prior access or privileges to the system.

|---|---|
| Public Exploit | Not confirmed |
| PoC Code | Not confirmed |
Implement strict input validation and length checks on HTTP headers, particularly the 'Cookie' header, to prevent buffer overflows. Consider deploying a web application firewall (WAF) to filter out suspicious requests.
No reliable network detection signature exists for this vulnerability class — apply the compensating controls above and the vendor patch. SAGE only publishes a network rule when a concrete on-the-wire signature can be grounded in the advisory.
This CVE violates CIP-007-R6 because it allows an unauthorized individual to gain control of the electronic security perimeter, which could compromise the integrity and availability of critical assets.
This CVE maps to SR 7.6 because it involves a vulnerability that can be exploited remotely to execute arbitrary code, which directly impacts the security requirements for protecting against unauthorized access and ensuring the integrity of industrial control systems.
Virtual patch generated by CITED Relevance SAGE. Validate in isolated environment before production deployment. Compensating control only - does not replace vendor patch.
