MEDIUM

MIT Kerberos 5 1.8.x-1.8.3 - Authenticated Signature Forgery via RC4 Key-Derivation Checksums

Title source: llm
STIX 2.1

Description

MIT Kerberos 5 (aka krb5) 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a (1) AD-SIGNEDPATH or (2) AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte stream-cipher operations.
