    CVE-2022-24403 (GCVE-0-2022-24403)

    Vulnerability from cvelistv5 – Published: 2023-12-05 13:54 – Updated: 2024-08-03 04:13
    VLAI
    Title
    De-anonymization attack in TETRA
    Summary
    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.
    Severity

    CVE-2022-24401 (GCVE-0-2022-24401)

    Vulnerability from cvelistv5 – Published: 2023-10-19 09:32 – Updated: 2024-08-03 04:13
    VLAI
    Title
    Keystream recovery for arbitrary frames in TETRA
    Summary
    Adversary-induced keystream re-use on TETRA air-interface encrypted traffic using any TEA keystream generator. IV generation is based upon several TDMA frame counters, which are frequently broadcast by the infrastructure in an unauthenticated manner. An active adversary can manipulate the view of these counters in a mobile station, provoking keystream re-use. By sending crafted messages to the MS and analyzing MS responses, keystream for arbitrary frames can be recovered.

    Vulnerability from cvelistv5 – Published: 2023-10-19 09:32 – Updated: 2024-09-12 20:31
    VLAI
    Title
    Intentionally weakened effective strength in TETRA TEA1
    Summary
    The TETRA TEA1 keystream generator implements a key register initialization function that compresses the 80-bit key to only 32 bits for usage during the keystream generation phase, which is insufficient to safeguard against exhaustive search attacks.
    Severity

    Title
    Ciphertext Malleability in TETRA
    Summary
    Lack of cryptographic integrity check on TETRA air-interface encrypted traffic. Since a stream cipher is employed, this allows an active adversary to manipulate cleartext data in a bit-by-bit fashion.
