CVSS v3.1
Official Description
Sudo 1.5 in Debian Linux 2.1 and Red Hat 6.0 allows local users to determine the existence of arbitrary files by attempting to execute the target filename as a program, which generates a different error message when the file does not exist.
Technical Analysis
CVE-1999-1496 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.
