Official description

IBM OpenPages with Watson 8.3 and 9.0 could provide weaker than expected security in a OpenPages environment using Native authentication. If OpenPages is using Native authentication an attacker with access to the OpenPages database could through a series of specially crafted steps could exploit this weakness and gain unauthorized access to other OpenPages accounts. IBM X-Force ID: 262594.

The underlying weakness: Storing Passwords in a Recoverable Format

The storage of passwords in a recoverable format makes them subject to password reuse attacks by malicious users. In fact, it should be noted that recoverable encrypted passwords provide no significant benefit over plaintext passwords since they are subject not only to reuse by malicious attackers but also by malicious insiders. If a system administrator can recover a password directly, or use a brute force search on the available information, the administrator can use the password on other accounts.

How developers prevent this class of flaw

  • Use strong, non-reversible encryption to protect stored passwords.
