SINEC Traffic Analyzer: Irrelevant Code
CVE-2025-40769 is a high-severity irrelevant code vulnerability in SINEC Traffic Analyzer from Siemens, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, without any action from a user. The record lists version V3.0 as the first without the flaw, so updating SINEC Traffic Analyzer to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.
