Apache HTTP Server Privilege Escalation Vulnerability (CVE-2019-0211)
Severity: high · Patch status: patched · Since 2021-11-03 · CVE-2019-0211
Apache HTTP Server, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute code with the privileges of the parent process (usually root) by manipulating the scoreboard. CISA added CVE-2019-0211 to its Known Exploited Vulnerabilities catalog on Nov 3, 2021, which means attackers are exploiting it in the wild.
What to do
- Apply updates per vendor instructions.
- US federal agencies must remediate by May 3, 2022 (BOD 22-01); treat that as the outer limit.
