Portal: Cross-Site Request Forgery
CVE-2024-26271 is a high-severity cross-site request forgery vulnerability in Portal from Liferay, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected Portal versions: 7.4.3.75 through 7.4.3.111; 7.4.3.111 through 7.4.3.75. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.38% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Digital Experience Platform to 2023.q3.6 or 2023.q4.3, whichever matches your release line, or a later version.
- Update Liferay Portal to 7.4.3.112 or a later version.
- Read the advisory on liferay.dev for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Cross-site request forgery (CSRF) vulnerability in the My Account widget in Liferay Portal 7.4.3.75 through 7.4.3.111, and Liferay DXP 2023.Q4.0 through 2023.Q4.2, 2023.Q3.1 through 2023.Q3.5, 7.4 update 75 through update 92 and 7.3 update 32 through update 36 allows remote attackers to (1) change user passwords, (2) shut down the server, (3) execute arbitrary code in the scripting console, (4) and perform other administrative actions via the _com_liferay_my_account_web_portlet_MyAccountPortlet_backURL parameter.

The underlying weakness: Cross-Site Request Forgery
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, use anti-CSRF packages such as the OWASP CSRFGuard. Another example is the ESAPI Session Management control, which includes a component for CSRF.
- Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
- Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
