CVE-2002-1658: Apache HTTP Server

Medium severity, CVSS 4.6. EPSS: 1.1% chance of exploitation in the next 30 days.

Buffer overflow in htdigest in Apache 1.3.26 and 1.3.27 may allow attackers to execute arbitrary code via a long user argument. NOTE: since htdigest is normally only locally accessible and not setuid or setgid, there are few attack vectors which would lead to an escalation of privileges, unless htdigest is executed from a CGI program. Therefore this may not be a vulnerability.

• Apache HTTP Server: version 1.3.1 only; version 1.3.3 only; version 1.3.4 only; version 1.3.6 only; version 1.3.9 only; version 1.3.11 only; …
