Description

This security bulletin contains information about 4 vulnerabilities.


1) OS Command Injection (CVE-ID: CVE-2024-57391)

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

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


The vulnerability allows a remote user to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation. A remote administrator can pass specially crafted data to the application and execute arbitrary OS commands on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Inefficient regular expression complexity (CVE-ID: CVE-2025-2811)

CWE-ID: CWE-1333 - Inefficient Regular Expression Complexity

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


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

3) Improper Authorization (CVE-ID: CVE-2025-2850)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass authorization checks.

The vulnerability exists due to improper authorization. A remote user on the local network can cause arbitrary file download of router in download interfaces.


4) Buffer overflow (CVE-ID: CVE-2025-2851)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the rpc in the plugins.so library. A remote user on the local network can trigger memory corruption and execute arbitrary code on the target system.
