Security Bulletin

This security bulletin contains information about 11 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU93540

Risk: Medium

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2024-38473

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to bypass authentication.

The vulnerability exists due to insufficient validation of user-supplied input when handling incorrect encoding in mod_proxy. A remote attacker can force the web server to pass request URLs with incorrect encoding to backend services.

Mitigation

Install updates from vendor's repository.

10) Information disclosure

EUVDB-ID: #VU93729

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-39884

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error when processing legacy content-type based configuration of handlers, such as "AddType" and similar configuration when files are requested indirectly. A remote attacker can send a specially crafted HTTP request and view contents of files, for example the source code of a PHP script can be served instead of interpreted.

Mitigation

Install updates from vendor's repository.
