Technical details
An incorrect authorization vulnerability (CWE-863) exists in the Credentials Manager functionality of Nozomi Networks Guardian and CMC versions prior to 26.3.0. The vulnerability stems from insufficient validation of user privileges when accessing credential entries. An authenticated remote attacker with limited privileges can enumerate, delete, and edit credential entries, though the actual plaintext credential values are not directly exposed. An attacker manipulating or deleting entries can disrupt authentication for dependent devices or indirectly obtain credentials through configuration manipulation. The vulnerability requires network access and valid user authentication; no user interaction is required. Patches are available in Guardian/CMC version 26.3.0 and later.
