Details

A vulnerability classified as problematic was found in calmkart Django-sso-server up to 057247929a94ffc358788a37ab99e391379a4d15. This vulnerability affects the function gen_rsa_keys of the file common/crypto.py. The manipulation leads to inadequate encryption strength. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available.

Mitigation
Architecture and Design

Use an encryption scheme that is currently considered to be strong by experts in the field.

CAPEC-112: Brute Force

In this attack, some asset (information, functionality, identity, etc.) is protected by a finite secret value. The attacker attempts to gain access to this asset by using trial-and-error to exhaustively explore all the possible secret values in the hope of finding the secret (or a value that is functionally equivalent) that will unlock the asset.

CAPEC-192: Protocol Analysis

An adversary engages in activities to decipher and/or decode protocol information for a network or application communication protocol used for transmitting information between interconnected nodes or systems on a packet-switched data network. While this type of analysis involves the analysis of a networking protocol inherently, it does not require the presence of an actual or physical network.

CAPEC-20: Encryption Brute Forcing

An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.
