Broken User Authentication☝️ — What you need to know Introduction API2:Broken User Authentication What is Broken User Authentication? Broken User Authentication can manifest in several issues. Whenever we come across an API endpoint that handles authentication we need to be extra careful since...

Revive Adserver: Use of a Broken or Risky Cryptographic Algorithm

revive-adserver utilizes a PRNG for session-token generation, this means that an attacker could theoretically be able to generate session tokens at random and take over accounts at random. This function does not generate cryptographically secure values, and should not be used for cryptographic...
