25) 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

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.

CVE-ID: CVE-2024-24806

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input when handling hostnames longer than 256 characters within the uv_getaddrinfo() function in src/unix/getaddrinfo.c and its windows counterpart src/win/getaddrinfo.c. A remote attacker can pass a specially crafted hostname to the application, which can be resolved to an attacker controlled IP address and initiate unauthorized requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

30) Insufficient verification of data authenticity

EUVDB-ID: #VU89351

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-34397

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

Exploit availability: No

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

The vulnerability exists due to missing authorization for D-Bus signals. When a GDBus-based client subscribes to signals from a trusted system service such as NetworkManager on a shared computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will wrongly interpret as having been sent by the trusted system service.
