Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Improper locking

EUVDB-ID: #VU108044

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-2817

CWE-ID: CWE-667 - Improper Locking

Exploit availability: No

Description

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

The vulnerability exists due to improper locking mechanism in Firefox Updater. A medium-integrity user process can  interfere with the SYSTEM-level updater by manipulating the file-locking behavior by injecting code into the user-privileged process. A local user or malicious software installed on the system can bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

openEuler: 24.03 LTS

firefox-debugsource: before 128.10.0-1

firefox-debuginfo: before 128.10.0-1

firefox: before 128.10.0-1

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) Protection Mechanism Failure

EUVDB-ID: #VU108046

Risk: High

CVSSv4.0: 6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2025-4083

CWE-ID: CWE-693 - Protection Mechanism Failure

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to insufficient process isolation when handling "javascript:" URI links. An attacker can trick the victim into clicking on a specially crafted link and execute content in the top-level document's process instead of the intended frame.

Mitigation

Install updates from vendor's repository.

3) Input validation error

EUVDB-ID: #VU108047

Risk: Medium

CVSSv4.0: 4.8 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2025-4084

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 insufficient escaping of the ampersand character in the "copy as cURL" feature. A remote attacker can trick the victim into copying a specially crafted URL and execute arbitrary commands on the system.

Note, the vulnerability affects Windows installations only.

Mitigation

Install updates from vendor's repository.
