Description

Adobe Genuine Software Integrity Service was affected by an Incorrect Authorization vulnerability that could result in a Security feature bypass. An attacker could have leveraged this vulnerability to bypass security measures and gain unauthorized limited write access. Exploitation of this issue did not require user interaction, but required the attacker to have access to the local environment the application is installed on.

  "executiveSummary": "An incorrect authorization vulnerability has been identified within the Adobe Genuine Software Integrity Service. This security flaw enables a malicious actor to achieve a security feature bypass, leading to unauthorized limited write access within the affected local environment.\nThe vulnerability directly impacts the Adobe Genuine Software Integrity Service, compromising its intended validation and enforcement mechanisms. The risk implication centers on the degradation of system integrity, as successful exploitation allows unauthorized modifications through restricted write capabilities.\nRegarding attacker capabilities and exploitation requirements, the adversary does not need any user interaction to execute the attack. However, the threat actor must already possess local access to the target host environment where the vulnerable application is installed. Consequently, the threat vector is constrained to local privilege escalation scenarios or post-compromise hardening bypasses rather than remote network exploitation.",
  "technicalDetails": "The vulnerability stems from improper authorization enforcement within the Adobe Genuine Software Integrity Service. Specifically, the component responsible for validating service operations fails to adequately verify the permissions and context of incoming local requests, leading to an incorrect authorization flaw.\nThe vulnerable component resides within the Adobe Genuine Software Integrity Service architecture, which handles validation routines and integrity checks for Adobe software installations. Due to the authorization validation failure, processes or local users interacting with the service can bypass intended security boundaries.\nThe attack flow proceeds as follows: First, the attacker establishes local access to the target operating system environment housing the vulnerable application. Second, the attacker interacts with the exposed local interfaces or inter-process communication (IPC) mechanisms managed by the Adobe Genuine Software Integrity Service. Third, by submitting specifically crafted local requests, the attacker leverages the incorrect authorization logic to circumvent the security feature enforcement. Finally, the service processes the unauthorized request without proper validation, granting the attacker unauthorized limited write access to protected resources or configuration areas governed by the service.\nRegarding constraints and requirements, the vulnerability requires local execution context, meaning network exposure is not a direct vector for initial exploitation. Authentication requirements depend on local operating system boundaries, but the core flaw allows actors operating within the local environment to exceed their intended authorization scope. The payload behavior involves issuing privileged local commands or file system modifications that the compromised service incorrectly permits. The resulting post-exploitation impact is constrained to unauthorized limited write access, which may facilitate further local system tampering or the persistence of unauthorized modifications within the application's operational scope."
