CVSS Release:
CVE-2025-12387: A vulnerability in the Pix-Link LV-WR21Q router's language module allows remote attackers to trigger a denial of service (DoS) by sending a specially crafted HTTP POST request containing non-existing language parameter. This renders the server unable to serve correct lang.js file, which causes administrator panel to not work, resulting in DoS until the language settings is reverted to a correct value. The Denial of Service affects only the administrator panel and does not affect other router functionalities. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version V108_108 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
The exploitability of CVE-2025-12387 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
No exploitability data is available for CVE-2025-12387.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-12387, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-12387, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
