CVE-2024-22892
📋 TL;DR
OpenSlides 4.0.15 uses a weak hashing algorithm to store user passwords, making them vulnerable to offline cracking attacks. This affects all OpenSlides 4.0.15 installations where user accounts exist. Attackers who gain access to the password database can potentially recover plaintext passwords.
💻 Affected Systems
- OpenSlides
📦 What is this software?
Openslides by Openslides
⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain password database and crack all passwords, gaining unauthorized access to all user accounts including administrative privileges, leading to complete system compromise.
Likely Case
Attackers with database access can crack weak passwords, gaining access to some user accounts and potentially escalating privileges within the OpenSlides application.
If Mitigated
With strong password policies and proper access controls, only weak passwords would be crackable, limiting the scope of compromise.
🎯 Exploit Status
Exploitation requires access to the password database, which typically requires some level of system access first.
