Login bypass vulnerability in Social Insurance, eCourt, and eHealth systems
A serious vulnerability has been discovered in several public administration systems, including Social Insurance and eHealth, allowing unauthorized access to user accounts. The attack can be executed in under a minute and bypasses two-factor authentication. This issue highlights significant flaws in the security testing of critical software integrations.
- ▪The vulnerability affects multiple public administration systems, including ZUS and CEZ.
- ▪Attackers need internet access, knowledge of the victim's PESEL number, and specific tools to exploit the vulnerability.
- ▪The research indicates a lack of adequate security testing for critical software integrations in these systems.
