Status: DeferredHigh (8.7)—

FileOptimizer 14.00.2524 contains a denial of service vulnerability that allows attackers to crash the application by manipulating the FileOptimizer32.ini configuration file. Attackers can overwrite the TempDirectory parameter with a 5000-character buffer to cause the application to crash when opening options.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques
