VAR-201712-0434
Vulnerability from variot - Updated: 2022-05-11 23:20wolfSSL prior to version 3.12.2 provides a weak Bleichenbacher oracle when any TLS cipher suite using RSA key exchange is negotiated. An attacker can recover the private key from a vulnerable wolfSSL application. This vulnerability is referred to as "ROBOT.". TLS implementations may disclose side channel information via discrepancies between valid and invalid PKCS#1 padding, and may therefore be vulnerable to Bleichenbacher-style attacks. wolfSSL Contains a cryptographic vulnerability.Information may be obtained. wolfSSL is prone to an information-disclosure vulnerability. An attacker can exploit this issue to perform man-in-the-middle attacks to obtain sensitive information, and perform unauthorized actions. Successful exploits will lead to other attacks. Versions prior to wolfSSL 3.12.2 are vulnerable
