Description
This security bulletin contains information about 5 vulnerabilities.
1) Code injection (CVE-ID: CVE-2025-65082)
CWE-ID: CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
CVSSv4: CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to affect web server behavior.
The vulnerability exists due to improper input validation when handling environment variables set via the Apache configuration. A local user can set specially crafted values that supersede variables calculated by the server for CGI programs.
2) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2025-59775)
CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input when AllowEncodedSlashes is "On" and MergeSlashes is "Off". A remote attacker can send a specially crafted HTTP request and force the web server into leaking NTLM hashes.
Note, the vulnerability affects Windows installations only.
3) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-43394)
CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Green
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input when handling UNC paths on Windows. A remote attacker can trick the application into initiating requests to arbitrary systems and potentially leak NTLM hashes to a malicious server via mod_rewrite or apache expressions that pass unvalidated request input.
Note, the vulnerability affects Windows installations only.
4) 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.
5) Improper input validation (CVE-ID: CVE-2026-34291)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Core component in Oracle HTTP Server. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
