CVE-2022-28615: 
Apache HTTP Server vulnerability analysis and mitigation

CVE-2022-28615 affects Apache HTTP Server 2.4.53 and earlier versions. The vulnerability was discovered when an extremely large input buffer provided to the apstrcmpmatch() function could cause a read beyond bounds, potentially leading to server crashes or information disclosure. While no code distributed with the server can be directly exploited, third-party modules or lua scripts that use apstrcmpmatch() may be hypothetically affected (Apache Advisory).

The vulnerability is classified with a CVSS 3.1 base score of 9.1 (Critical) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H. The issue stems from a read beyond bounds vulnerability in the apstrcmpmatch() function when processing extremely large input buffers. The vulnerability requires no privileges or user interaction and can be exploited remotely (NVD, NetApp Advisory).

Successful exploitation of this vulnerability could lead to server crashes and potential information disclosure. The high CVSS score reflects the critical nature of the potential impact, particularly concerning confidentiality and availability of the system (NetApp Advisory).

The vulnerability was fixed in Apache HTTP Server version 2.4.54. Users are recommended to upgrade to this version or later to address the issue. The fix was included in various distribution updates including Fedora 35 (httpd-2.4.54-1.fc35) and Fedora 36 (httpd-2.4.54-3.fc36) (Fedora Update).
