Name of the Vulnerable Software and Affected Versions: jose2go versions prior to 1.6.0 Description: The issue allows attackers to cause a denial of service, specifically CPU consumption, via a large p2c also known as PBES2 Count value in a PBES2 encrypted JWE blob. This can occur when an...

The vulnerability of the PBES2 encryption algorithm in the jwx library allows a perpetrator to cause a service failure.

The vulnerability of the PBES2 encryption algorithm in the jwx library is related to an uncontrolled resource consumption during the processing of the p2c parameter, which determines the number of iterations required to obtain the key. Exploiting this vulnerability could allow a remote attacker t...

Microsoft Incident Response lessons on preventing cloud identity compromise

Microsoft observed a surge in cyberattacks targeting identities in 2023, with attempted password-based attacks increasing by more than tenfold in the first quarter of 2023 compared to the same period in 2022.
