CVE-2023-40104

Status: AnalyzedHigh (7.5)—

In ca-certificates, there is a possible way to read encrypted TLS data due to untrusted cryptographic certificates. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

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).
