Exploitation Probability (EPSS)

Elevated risk
1.06%

60th percentile - higher than 60% of all known CVEs

Summary

The SimpleCaptcha implementation in Liferay Portal 7.3.4, 7.3.5 and Liferay DXP 7.3 before fix pack 1 does not invalidate CAPTCHA answers after use. This allows remote attackers to repeatedly perform actions protected by a CAPTCHA challenge by reusing the same CAPTCHA answer.

Risk Assessment

The organization is exposed to automated attacks such as spam, brute-force, or fake account registration that should be prevented by the CAPTCHA mechanism.

Recommendation

Immediately update Liferay Portal to version 7.3.6 or later, and Liferay DXP to a version with fix pack 1 or higher.
