ZoneMinder vulnerabilities

ZoneMinder prior to 1.39.2, 1.38.2, and 1.36.40 interpolates an unvalidated monitor Device field into shell commands in PHP and Perl control paths. An authenticated user with monitor-create or monitor-edit permission can save a Local monitor whose Device Path contains shell metacharacters, leading to arbitrary command execution as the web server user.

CVE-2016-10206 is a CSRF vulnerability in Zoneminder 1.30 and earlier that allows remote attackers to hijack user authentication for requests that change passwords and possibly other unspecified impacts.

Session fixation vulnerability in Zoneminder 1.30 and earlier allows remote attackers to hijack web sessions via the ZMSESSID cookie.

ZoneMinder versions 1.30 and 1.29 are vulnerable to CSRF attacks, allowing a remote attacker to make changes to the web application as the currently logged-in user. The attacker can silently create a new admin user, enabling further attacks.

ZoneMinder is a free, open source closed-circuit television software application. Prior to 1.38.3, downloadEvents() manually wraps a monitor Name value in single quotes instead of using escapeshellarg() before placing it in shell commands when a user with monitor-create or monitor-edit permission stores a monitor Name containing shell metacharacters and a user with Events View permission exports that monitor's events. In this attack mechanism, the stored monitor Name reaches both the ffmpeg concatenation command and the tar or zip archive command and breaks out of manual quoting. Arbitrary commands execute as the web server user.

CVE-2016-10204 is an SQL injection vulnerability in Zoneminder 1.30 and earlier that allows remote attackers to execute arbitrary SQL commands via the limit parameter in a log query request to index.php.

ZoneMinder prior to 1.38.3 concatenates the attacker-controlled exportFile request parameter into a shell command without neutralizing shell metacharacters in exportEvents(). An authenticated user with View Events or View Snapshots permission can submit a crafted export request and execute arbitrary OS commands as the web server user.

ZoneMinder versions 1.34.0 through 1.36.38 mishandles failed token authentication in web/includes/auth.php. validateToken() returns false for a malformed or invalidly signed token, but the caller assigns that value to the global $user variable; because web/index.php tests isset($user), boolean false is treated as a present user and the normal login redirect is skipped.

ZoneMinder before 1.38.4 fails to apply per-monitor access restrictions in the FramesController index endpoint. Authenticated users with Events view permission can call the frames API to list frame records from monitors they are denied access to, disclosing event and frame metadata across monitor boundaries.

ZoneMinder before 1.38.4 contains static buffer overflow vulnerabilities in RemoteCameraHttp::GetResponse() that allow malicious HTTP cameras or intercepting attackers to overflow fixed-size buffers by sending oversized response headers. Attackers can send crafted HTTP responses with oversized status messages, Connection headers, Content-Type values, or multipart boundaries to corrupt parser state and crash the capture process or corrupt memory.

ZoneMinder versions 1.37.0 before 1.38.0 contain a path traversal vulnerability in the files view that allows authenticated users to read arbitrary files. The path parameter is not properly validated before being passed to output_file, enabling attackers with Events view permission to access sensitive files like configuration files containing database credentials.

ZoneMinder versions prior to 1.36.39, 1.38.4, and 1.39.11 allow an authenticated low-privileged user with coarse Events=View and/or Snapshots=View permissions to directly fetch media for events belonging to monitors they are not allowed to access. The normal UI hides the restricted monitor, but direct event media views accept an arbitrary eid and stream media without enforcing event/monitor-level ACL.

An authenticated OS command injection vulnerability exists in ZoneMinder's event export functionality. The exportFile HTTP request parameter is passed unsanitized into a shell command executed via PHP's exec(), allowing any authenticated user with View Events permission to execute arbitrary operating system commands on the server.

A remote code execution vulnerability in ZoneMinder 1.39.17 allows any authenticated user to execute OS commands by exploiting a broken permission check in the Filter class. canEdit() and canDelete() call nonexistent methods, causing PHP __call() to return truthy and bypass the check.

A Remote Code Execution (RCE) vulnerability in ZoneMinder through version 1.36.33 allows an attacker to create a new .php log file in the language folder. By executing a crafted payload, the attacker can escalate privileges and execute arbitrary commands on the remote system.
