CVE-2023-26035 is a high-severity vulnerability found in ZoneMinder, a widely used open-source closed-circuit television software application for Linux. This vulnerability allows unauthenticated remote code execution due to missing authorization checks on snapshot actions. Attackers can exploit this flaw by passing an object to create a new monitor instead of providing an existing monitor's ID, which ultimately leads to executing arbitrary commands on the host system. The vulnerability affects all versions prior to 1.36.33 and 1.37.33, necessitating immediate attention from administrators.
The CVSS score for this vulnerability is 7.2, indicating a high severity level. This score reflects the potential impact of unauthorized access to sensitive system functions, enhancing the urgency for organizations to apply the necessary patches. The issue has been resolved in versions 1.36.33 and 1.37.33, which include the required authorization checks to prevent this type of exploitation.
Risk to organizations includes unauthorized access to critical system functions, leading to possible data breaches or system compromise. Given the nature of the vulnerability, it is crucial for organizations using affected versions of ZoneMinder to prioritize patching to safeguard their systems against potential attacks. As of the latest update, this vulnerability is not known to be actively exploited in the wild, but the availability of public proof-of-concept (PoC) exploits heightens the risk.
Organizations should prioritize patching immediately. The lack of proper permissions checks on snapshot actions creates a significant attack vector that could be exploited by malicious actors. Security teams should assess their deployments and ensure that all systems are updated to the latest versions to mitigate this vulnerability effectively.
This vulnerability highlights the need for robust security practices and regular updates to software systems to manage and mitigate risks effectively.
Vulnerability Details
The official CVE description states that this vulnerability allows unauthenticated remote code execution through missing authorization checks. Versions of ZoneMinder prior to 1.36.33 and 1.37.33 are affected. The vulnerability is classified under CWE-862 and has a CVSS score of 7.2. The vulnerability was published on February 25, 2023.
Technical Analysis
The root cause of CVE-2023-26035 is the absence of permission checks within the snapshot action of ZoneMinder. The attack vector is network-based, requiring low complexity to exploit with no privileges necessary. User interaction is also not required, making it easier for attackers to leverage this vulnerability. The vulnerability affects confidentiality and integrity, with a low impact on availability.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-26035 is significant, as attackers may leverage this vulnerability to execute arbitrary code on vulnerable systems, leading to potential unauthorized access and control. The blast radius includes any organization utilizing affected versions of ZoneMinder, making it critical for organizations to address this vulnerability within their patch cycles. Given the high CVSS score and the potential for exploitation, organizations should address this vulnerability in priority patch cycles.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
ZoneMinder versions prior to 1.36.33 and 1.37.33 are vulnerable to this issue. Organizations should ensure they are running the latest versions to mitigate the risk associated with this vulnerability.
Mitigation & Remediation
To mitigate this vulnerability, organizations should upgrade to ZoneMinder versions 1.36.33 or 1.37.33. If a patch is unavailable, organizations may consider implementing network controls to restrict access to the application and monitor logs for any unusual activities. Additionally, regular security assessments, such as continuous penetration testing, can help identify additional vulnerabilities.
Detection Guidance
Organizations should monitor logs for any unexpected snapshot actions or commands being executed that do not align with normal operations. Behavioral anomalies, such as unusual access patterns or unauthorized attempts to create monitors, should be investigated. Additionally, monitoring network traffic for anomalous requests to the ZoneMinder application can help detect potential exploitation attempts.
AppSecure Threat Intelligence Insight
CVE-2023-26035 signifies a critical need for organizations to enhance their security practices, particularly around access controls. The existence of public PoCs indicates that this vulnerability is well-known, and attackers may attempt to exploit it.
Security teams should incorporate lessons from this incident into their vulnerability management practices, ensuring that regular updates and security reviews are part of their operational protocols. Furthermore, adopting a proactive security stance through methodologies such as penetration testing methodologies can strengthen defenses against similar vulnerabilities.
Additionally, organizations should remain vigilant about the evolving threat landscape and continuously improve their security posture through training and awareness initiatives.
