Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) OS Command Injection

EUVDB-ID: #VU99357

Risk: Low

CVSSv4.0: 5.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-9287

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper input validation in the venv module when creating a virtual environment. A local user can pass specially crafted strings to the application and execute arbitrary OS commands on the target system.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Red Hat Enterprise Linux for ARM 64: 9

Red Hat Enterprise Linux for Power, little endian: 9

Red Hat Enterprise Linux for IBM z Systems: 9

Red Hat Enterprise Linux for x86_64: 9

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Input validation error

EUVDB-ID: #VU100516

Risk: Medium

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

CVE-ID: CVE-2024-11168

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass security restrictions.

The vulnerability exists due to insufficient validation of bracketed hosts (e.g. []) within the urllib.parse.urlsplit() and urlparse() functions allowing hosts that weren't IPv6 or IPvFuture. A remote attacker can pass specially crafted IP address to the application to bypass implemented IP-based security checks or perform SSRF attacks.

Mitigation

Install updates from vendor's website.
