Description

CAI Content Credentials is affected by an Improper Input Validation vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files and directories outside the intended access scope. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

  "executiveSummary": "The CAI Content Credentials component contains an Improper Input Validation vulnerability that enables arbitrary file system read operations.\nThis vulnerability is categorized as a path traversal or arbitrary file read issue, allowing unauthorized access to sensitive files residing outside of the application's intended directory structure.\nThe flaw impacts the CAI Content Credentials framework. Successful exploitation grants an attacker the ability to exfiltrate system files or sensitive configuration data stored on the host filesystem.\nThe risk is categorized as high, as it compromises the confidentiality of data processed by the affected product. The exploitation process requires user interaction, specifically mandating that a victim must open a maliciously crafted file designed to trigger the vulnerability. There is no requirement for pre-existing authentication or elevated privileges from the attacker's perspective, provided the user interaction component is met.",
  "technicalDetails": "The vulnerability resides within the input processing logic of CAI Content Credentials, specifically where the component handles file path references provided within processed metadata or asset payloads.\nThe root cause is identified as an Improper Input Validation flaw, where the software fails to adequately sanitize or validate user-supplied file path information before utilizing it in filesystem operations.\nThe attack flow initiates when an attacker distributes a malicious file containing crafted credentials or metadata. When a victim opens this file within the CAI Content Credentials environment, the application parses the malicious input.\nDue to the lack of sufficient path normalization or blacklisting of directory traversal sequences (e.g., '../'), the application resolves the malicious path against the underlying file system. This allows the application to traverse beyond its designated sandbox or working directory to reach restricted system files.\nThe vulnerable component performs file I/O operations based on the unvalidated input. By embedding traversal sequences, an attacker can coerce the application into reading sensitive files, such as configuration files, credential stores, or system logs, which are then either displayed or processed in a way that exposes the contents to the attacker.\nThis vulnerability does not require network exposure in the traditional sense; the attack is localized to the environment where the malicious file is parsed. However, if the output of the file read is transmitted back to a remote entity, the impact is effectively a remote information disclosure. No specific authentication is required to initiate the attack; the primary vector is the successful deception of a user into opening the malformed file.\nPost-exploitation, an attacker can leverage the arbitrary read capability to gather intelligence on the host environment, extract environmental variables, or gain insight into internal system architectures, which may facilitate further privilege escalation or lateral movement within the system."
