SB2025121940 - Anolis OS update for httpd

Description

This security bulletin contains information about 2 vulnerabilities.

1) Integer overflow (CVE-ID: CVE-2025-55753)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to an integer overflow in mod_md (ACME) in the case of failed ACME certificate renewal. The web server will set the backoff timer becoming 0 after a number of failures (~30 days in default configurations), leading to a denial of service condition.

2) Improper Neutralization of Server-Side Includes (SSI) Within a Web Page (CVE-ID: CVE-2025-58098)

CWE-ID: CWE-97 - Improper Neutralization of Server-Side Includes (SSI) Within a Web Page

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear

The vulnerability allows a remote attacker to execute arbitrary commands.

The vulnerability exists due to insufficient input validation with Server Side Includes (SSI) enabled and mod_cgid (but not mod_cgi). The web server passes the shell-escaped query string to #exec cmd="..." directives. A remote attacker can send a specially crafted HTTP request to the server and potentially execute arbitrary code.

Remediation

Install update from vendor's website.
