Use of a Broken or Risky Cryptographic Algorithm vulnerability in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix on all (pkix modules), Legion of the Bouncy Castle Inc. BCPKIX-FIPS bcpkix on All (pkix modules), Legion of the Bouncy Castle Inc. BCPIX-LTS bcpkix on All (pkix modules).
This vulnerability is associated with program files JcaContentVerifierProviderBuilder.Java, JcaContentVerfierProviderBuilder.Java.
This issue affects BC-JAVA: from 1.67 before 1.80.2, from 1.81 before 1.81.1, from 1.82 before 1.84; BCPKIX-FIPS: from 2.0.6 before 2.0.11, from 2.1.7 before 2.1.11; BCPIX-LTS: from 2.73.7 before 2.73.11.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft CompositeVerifier implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially compromising the authenticity and integrity of data.
Отчет
To exploit this issue, an attacker needs to submit a crafted payload or token containing an empty signature sequence to an application using the CompositeVerifier for cryptographic validation. An attack typically requires the application to process this malformed data and improperly accept the empty sequence as a valid signature, bypassing standard verification checks.
The primary impact of this vulnerability is the compromise of data authenticity and integrity, allowing an attacker to forge digital signatures and impersonate trusted entities.
Меры по смягчению последствий
To mitigate this flaw, check that the signature sequence is not empty before passing any data to the CompositeVerifier for cryptographic validation. If the sequence is empty or null, explicitly reject the payload before it is processed.
