CVE-2012-2742

Status: ModifiedMedium (5)—

Revelation 0.4.13-2 and earlier uses only the first 32 characters of a password followed by a sequence of zeros, which reduces the entropy and makes it easier for context-dependent attackers to crack passwords and obtain access to keys via a brute-force attack.

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).
