An issue was discovered in eteams OA v4.0.34. Because the session is not strictly checked, the account names and passwords of all employees in the company can be obtained by an ordinary account. Specifically, the attacker sends a jsessionid value for URIs under app/profile/summary/.

Exploit prediction

1.03% chance of exploitation in the next 30 days, higher than 63% of all scored CVEs (FIRST EPSS, 2026-11-08).
