PetitPotam NTLM Relay Attack
THE THREAT PetitPotam is a variant of NTLM Relay attacks discovered by security researcher Gilles Lionel. Proof of Concept code released last week [1] relies on the Encrypting File System Remote (EFSRPC) protocol to provoke a Windows host into performing an NTLM authentication request against an attacker-controlled server, exposing NTLM authentication details or authentication certificates.…

SAML Authentication Vulnerability

1 min read

Researchers have discovered a vulnerability affecting Single Sign-On (SSO) systems that rely on Security Assertion Markup Language (SAML). SAML is a standard for authenticating end users to web applications. If successfully exploited, an attacker would be able to impersonate a legitimate user and obtain privileged information. There are a variety of different methods and libraries that employ the SAML standard for SSO, requiring a security fix for each affected library. This particular attack requires an attacker to have an account already created. The attacker then modifies their account name to impersonate another individual.

What you should do about it

Additional information

The SAML vulnerability takes advantage of libraries incorrectly parsing commented strings and XML canonicalization for signing authentication tokens. The attackers are able to impersonate a legitimate user without altering the cryptographic signature.
