A heap-based buffer overflow vulnerability in Fortinet FortiAnalyzer Cloud 7.6.2 through 7.6.4, FortiManager Cloud 7.6.2 through 7.6.4 may allow a remote unauthenticated attacker to execute arbitrary code or commands via specifically crafted requests. Successful exploitation would require a large amount of effort in preparation because of ASLR and network segmentation

Detection & IOCsextracted from sources · hover to see the quote

→Target process/daemon: the vulnerability resides in the 'oftpd' daemon on affected Fortinet products; monitor for anomalous activity or crashes in this process ↗
→Exploitation vector is remote unauthenticated requests; inspect inbound traffic to FortiAnalyzer Cloud and FortiManager Cloud (versions 7.6.2–7.6.4) for unusually large or malformed FTP-related requests targeting the oftpd service ↗

·Affected versions are FortiAnalyzer Cloud 7.6.2 through 7.6.4 and FortiManager Cloud 7.6.2 through 7.6.4; ensure patching or mitigation is applied to these specific version ranges ↗
·Exploitation difficulty is high due to ASLR and network segmentation mitigations already in place; however, a determined attacker with sufficient preparation time may still succeed ↗
