Description

CAI Content Credentials is affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') 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 visit a maliciously crafted URL or interact with a compromised web page.

  "executiveSummary": "CAI Content Credentials is affected by an Improper Limitation of a Pathname to a Restricted Directory vulnerability, commonly known as path traversal. This security flaw enables threat actors to achieve arbitrary file system read capabilities. Successfully exploiting this vulnerability allows an attacker to gain unauthorized access to sensitive files and directories located outside the designated and restricted access scope of the application.\nThe risk implication is severe, as exposure of sensitive system files, configuration data, or internal resources can facilitate further compromise. The attacker capabilities include unauthorized data exfiltration of arbitrary files accessible to the application process. However, exploitation is contingent upon specific user interaction prerequisites. A victimized user must be induced to visit a maliciously crafted URL or interact directly with a compromised web page controlled by the attacker.\nThe affected system is CAI Content Credentials. Organizations utilizing this product face potential exposure of sensitive information if remediation or defensive controls are not properly implemented. The combination of arbitrary file read and user interaction vectors highlights the necessity for robust input validation and path sanitization measures within the affected software architecture.",
  "technicalDetails": "The vulnerability stems from an Improper Limitation of a Pathname to a Restricted Directory within CAI Content Credentials. The root cause lies in the application's failure to adequately sanitize, validate, or restrict user-supplied input utilized in file system operations. When the application processes path parameters or resource identifiers without enforcing strict boundary checks, it permits traversal sequences such as dot-dot-slash patterns to navigate upward through the directory hierarchy.\nThe vulnerable component is responsible for handling file access requests and resolving file paths based on inputs received via web interfaces or URL parameters. Because the software does not properly canonicalize paths or verify that the resolved destination resides strictly within the intended root directory, an attacker can construct relative or absolute path sequences to target arbitrary system files.\nThe exploitation method relies on web-based attack vectors requiring user interaction. The attack flow proceeds as follows: First, the attacker crafts a malicious URL containing specially designed path traversal sequences targeting sensitive system files outside the web root or restricted access scope. Second, the attacker induces a victim to visit this maliciously crafted URL or interact with a compromised web page that triggers the vulnerable request within the victim's context. Third, the application processes the malicious input, resolving the traversal sequences to access the targeted file on the underlying file system. Fourth, the application retrieves the contents of the arbitrary file and returns them to the requester or exposes them via the application interface, leading to unauthorized disclosure of sensitive data.\nRegarding operational context, the network exposure involves web-facing interfaces or components capable of processing external HTTP requests or user-driven interactions. Authentication and privilege requirements depend on the specific endpoint implementation, but path traversal vulnerabilities are frequently exploitable by unauthenticated remote attackers provided the victim interaction requirement is satisfied. The payload behavior involves directory traversal strings designed to traverse the file system structure. The post-exploitation impact includes the compromise of confidentiality through the unauthorized read access of sensitive configuration files, system data, or internal application assets."
