CVE-2025-3526: SessionClicks in Liferay Portal 7.0.0 through 7.4.3.21, and Liferay DXP 7.4 GA through update 9, 7.3 GA through update 25, and older unsuppo

Noroxi assessment

Priority: Monitor (action score 34/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.64% (FIRST EPSS); higher than 50.5% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: com.liferay.portal:com.liferay.portal.kernel (Maven) 38.0.0.

Low priority for now. Upgrade to com.liferay.portal:com.liferay.portal.kernel (Maven) 38.0.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

SessionClicks in Liferay Portal 7.0.0 through 7.4.3.21, and Liferay DXP 7.4 GA through update 9, 7.3 GA through update 25, and older unsupported versions does not restrict the saving of request parameters in the HTTP session, which allows remote attackers to consume system memory leading to denial-of-service (DoS) conditions via crafted HTTP requests.

Root cause

Code that parses nested structures sets no depth or size limit. A small input can turn into a disproportionate processing load.
