Detailsinfo

A vulnerability was found in ETSI TETRA Standard TA61. It has been declared as problematic. Affected by this vulnerability is an unknown code of the component Identity Handler. The manipulation with an unknown input leads to a risky encryption vulnerability. The CWE definition for the vulnerability is CWE-327. The product uses a broken or risky cryptographic algorithm or protocol. As an impact it is known to affect confidentiality. The summary by CVE is:

The TETRA TA61 identity encryption function internally uses a 64-bit value derived exclusively from the SCK (Class 2 networks) or CCK (Class 3 networks). The structure of TA61 allows for efficient recovery of this 64-bit value, allowing an adversary to encrypt or decrypt arbitrary identities given only three known encrypted/unencrypted identity pairs.

The weakness was published 12/05/2023 by Midnight Blue. This vulnerability is known as CVE-2022-24403 since 02/04/2022. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.
