Vulnerability Data

The ProfileGrid plugin for WordPress is vulnerable to unauthorized decryption of private information in versions up to, and including, 5.5.0. This is due to the passphrase and iv being hardcoded in the 'pm_encrypt_decrypt_pass' function and used across all sites running…

the plugin. This makes it possible for authenticated attackers, with administrator-level permissions or above to decrypt and view users' passwords. If combined with another vulnerability, this can potentially grant lower-privileged users access to users' passwords.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SA-12 Supply Chain Protection
addresses: CWE-321

Supply chain protection includes scrutiny of cryptographic implementations, reducing hard-coded keys planted by untrusted vendors.

SA-4 Acquisition Process
addresses: CWE-321

Functional and assurance requirements specified in acquisition can prohibit hard-coded cryptographic keys in delivered products.

SC-12 Cryptographic Key Establishment and Management
addresses: CWE-321

Proper key establishment and management processes directly preclude embedding static cryptographic keys in source code or binaries.

SC-17 Public Key Infrastructure Certificates
addresses: CWE-321

Approved PKI issuance and trust stores replace ad-hoc or hard-coded keys with properly managed, signed certificates.

SR-6 Supplier Assessments and Reviews
addresses: CWE-321

Assessments can uncover and prevent suppliers from shipping components that contain hard-coded cryptographic keys.

PR.DS-01 partial match
blocks

Data-at-rest protection policies require proper key management and therefore discourage hard-coded keys.

PR.DS-02 partial match
blocks

Data-in-transit protection similarly depends on non-hard-coded keys for encryption.

PR.PS-01 partial match
blocks

Configuration baselines and reviews can prohibit hard-coded keys in deployed artifacts.

PR.PS-06 partial match
blocks

Secure-SDLC activities such as code review and secret scanning directly prevent embedding static keys.
