Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU93540

Risk: Medium

CVSSv3.1: 4.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:P/RL:O/RC:C]

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

Update the affected package apache2 to the latest version.

2) Input validation error

EUVDB-ID: #VU93541

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-38474

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input in mod_rewrite when parsing encoded question marks in backreferences. A remote attacker can execute scripts in directories permitted by the configuration but not directly reachable by any URL or source disclosure of scripts meant to only to be executed as CGI.

Mitigation

Update the affected package apache2 to the latest version.

3) Information disclosure

EUVDB-ID: #VU93729

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

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

Update the affected package apache2 to the latest version.
