Cryptographic Weakness

thinbus-srp is vulnerable to cryptographic weakness. The vulnerability is due to a protocol compliance bug where the client generates only 252 bits of entropy instead of the intended 2048 bits, which allows an attacker to exploit the reduced security margin and potentially break the authenticatio...

Insufficient Entropy

Overview thinbus-srp is a Secure Remote Password SRP SRP6a implementation. Affected versions of this package are vulnerable to Insufficient Entropy in the toHex function. An attacker can reduce the security margin of the protocol and potentially compromise session confidentiality by exploiting th...

The Thinbus Javascript Secure Remote Password (SRP) Client Generates Fewer Bits of Entropy Than Intended

Impact A protocol compliance bug in thinbus-srp-npm versions prior to 2.0.1 causes the client to generate a fixed 252 bits of entropy instead of the intended bit length of the safe prime defaulted to 2048 bits. RFC 5054 states in section 2.5.4 Client Key Exchange The client key exchange message...
