CVSSv4.0: 8.1 [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:P/U:Green]

CVE-ID: CVE-2024-45337

CWE-ID: CWE-285 - Improper Authorization

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to gain unauthorized access to the application.

The vulnerability exists due to improper authorization caused by improper usage of the ServerConfig.PublicKeyCallback callback. A remote attacker can bypass authorization in certain cases and gain access to the application.

Mitigation

Install updates from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

3) Out-of-bounds write

EUVDB-ID: #VU19178

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-12900

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the BZ2_decompress() function in decompress.c. A remote attacker can create a specially crafted archive, trick the victim into opening it using the affected library, trigger out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Install updates from vendor's website.

4) 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

CPE2.3 External links

https://access.redhat.com/errata/RHSA-2025:0723


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.

5) 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.
