A vulnerability was detected in cijliu librtsp up to 2ec1a81ad65280568a0c7c16420d7c10fde13b04. The impacted element is the function rtsp_parse_request. The manipulation results in buffer overflow. Attacking locally is a requirement. This product takes the approach of rolling releases to provide continuous delivery. Therefore, version details for affected and updated releases are not available. The vendor was contacted early about this disclosure but did not respond in any way.
The severity level of this vulnerability is classified as low, with a CVSS base score of 1.9. Although the vulnerability has a low severity classification, organizations should remain vigilant and assess their exposure to this issue as part of their overall security posture.
Risk to organizations includes potential unauthorized access to sensitive data or system resources if the vulnerability is exploited. Therefore, even low-severity vulnerabilities should not be overlooked, especially in environments where security is paramount.
Organizations should prioritize patching immediately. Regularly updating and monitoring systems for vulnerabilities can help mitigate risks associated with known issues.
Currently, there is no known exploit for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should still assess their systems for exposure.
Vulnerability Details
The CVE-2026-1109 vulnerability is classified under CWE-119 and CWE-120, which pertain to buffer overflow issues. The attack vector is local, meaning that an attacker must have local access to exploit the vulnerability. The vulnerability allows for low privileges required (low) and does not require user interaction.
The CVSS score of this vulnerability varies across different versions, with a base score of 1.9 in CVSS 4.0 and a base score of 7.8 in CVSS 3.1 from NVD. This discrepancy suggests that while the vulnerability is assessed as low in some contexts, it could have more significant implications in others.
Technical Analysis
The root cause of the vulnerability lies in the rtsp_parse_request function, which is susceptible to buffer overflow attacks. Attackers can exploit this vulnerability by sending specially crafted requests to the vulnerable function, leading to potential data corruption or unexpected behavior within the application.
The attack complexity is rated as low, indicating that it may not require advanced skills to exploit. Additionally, the vulnerability requires low privileges, meaning that an authenticated user could potentially exploit it.
The confidentiality, integrity, and availability impacts are all assessed as low, indicating limited risk to organizational assets if the vulnerability is exploited. However, organizations should still be cautious, as low-severity vulnerabilities can serve as entry points for more significant attacks.
Risk & Impact Analysis
Real-world deployment risk associated with CVE-2026-1109 includes the potential for unauthorized access and exploitation of sensitive data. Organizations using the affected product should be aware of the possibility of exploitation if an attacker gains local access.
The urgency assessment based on the CVSS score indicates that organizations should address this vulnerability in their routine maintenance schedules. Even though it is classified as low severity, the implications of exploitation can lead to more significant risks.
