Detailsinfo

A vulnerability, which was classified as critical, has been found in Core.ai Phoenix Code up to 4.0.3. This issue affects an unknown functionality of the component com.apple.security.cs.disable-library-validation. The manipulation of the argument DYLD_INSERT_LIBRARIES with an unknown input leads to a default permission vulnerability. Using CWE to declare the problem leads to CWE-276. During installation, installed file permissions are set to allow anyone to modify those files. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The Phoenix Code's configuration on macOS, specifically the presence of entitlements: "com.apple.security.cs.allow-dyld-environment-variables" and "com.apple.security.cs.disable-library-validation" allows for Dynamic Library (Dylib) injection. A local attacker with unprivileged access can use environment variables like DYLD_INSERT_LIBRARIES to successfully inject code in application's context and bypass Transparency, Consent, and Control (TCC). Acquired resource access is limited to previously granted permissions by the user. Access to other resources beyond granted-permissions requires user interaction with a system prompt asking for permission. This issue was fixed in commit 0c75fb57f89d0b7d9b180026bc2624b7dcf807da
