vchkpw program in vpopmail before version 4.8 does not properly cleanse an untrusted format string used in a call to syslog, which allows remote attackers to cause a denial of service via a USER or PASS command that contains arbitrary formatting directives.
Technical Analysis
CVE-2000-0583 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
