Description
This security bulletin contains information about 3 vulnerabilities.
1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-43204)
CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)
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:U/U:Clear
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in mod_proxy . A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Note, the vulnerability exploitation requires an unlikely configuration where mod_headers is configured to modify the Content-Type request or response header with a value provided in the HTTP request.
2) 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.
3) HTTP response splitting (CVE-ID: CVE-2024-42516)
CWE-ID: CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not correctly process CRLF character sequences. A remote attacker with ability to manipulate the Content-Type response headers of applications hosted or proxied by the server can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
Note, this vulnerability exists due a missing fix for #VU88151 (CVE-2023-38709).
