Status: ModifiedHigh (7.8)—

A CWE-125: Out-of-bounds read vulnerability exists inIGSS Definition (Def.exe) V15.0.0.21140 and prior that could result in loss of data or remote code execution due to missing length checks, when a malicious WSP file is being parsed by IGSS Definition.

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).
