7.2
CVSS v3.1
Official Description
Buffer overflow in cfingerd 1.4.3 and earlier with the ALLOW_LINE_PARSING option enabled allows local users to execute arbitrary code via a long line in the .nofinger file.
Technical Analysis
CVE-2001-0735 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2001-0735. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
