CVE-2001-0040 describes a local denial-of-service vulnerability in apcupsd, the APC UPS daemon, affecting apc apcupsd products. The vulnerability arises because apcupsd saves its process ID in a world-writable file, allowing a local attacker to terminate an arbitrary process by manipulating the apcupsd.pid file. This has a low CVSS score of 2.1 (AV:L/AC:L/Au:N/C:N/I:N/A:P), indicating local access, low attack complexity, and a potential for partial availability impact. While not actively exploited in the wild and not on the KEV catalog, an ExploitDB entry (EDB-251) exists, and the CVE has garnered significant community discussion with 10 mentions.
