Published: 07 October 2022
Summary
CVE-2022-39290 is a high-severity Improper Authentication (CWE-287) vulnerability in Zoneminder Zoneminder. Its CVSS base score is 8.0 (High).
Operationally, ranked in the top 9.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
ZoneMinder, an open-source CCTV software application, contains a CSRF bypass vulnerability in affected versions. Authenticated users can circumvent CSRF protections by altering requests to the web application, specifically by switching HTTP POST methods to GET and stripping the CSRF key from the request. This flaw is tracked as CWE-287 and carries a CVSS 3.1 score of 8.0.
An attacker with the ability to influence or control requests from an authenticated user can leverage HTTP GET operations to execute actions that lack CSRF safeguards. The result is that an authenticated user may be induced to perform unintended operations on the ZoneMinder instance, potentially leading to high-impact changes in confidentiality, integrity, and availability.
The project’s security advisory and associated commits recommend immediate upgrade to a patched release, noting that no workarounds are available. Public references include the GitHub advisory GHSA-xgv6-qv6c-399q and the fixing commit c0a4c05e84eea0f6ccf7169c014efe5422c9ba0d. The EPSS score has remained flat at 0.0521 with no material increase observed after disclosure.

removing the CSRF key from the request. An attacker can take advantage of this by using an HTTP GET request to perform actions with no CSRF protection. This could allow an attacker to cause an authenticated user to perform unexpected actions on the web application. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
