CVE-2022-28614: Apache HTTP Server

Medium severity, CVSS 5.3. EPSS: 5% chance of exploitation in the next 30 days.

The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against current headers to resolve the issue.

Affected products

• Apache HTTP Server: up to and including 2.4.53
• Fedoraproject Fedora: version 35 only; version 36 only
• Netapp Clustered Data Ontap: affected versions not specified
