CVE-2024-25610: Liferay Portal has a Stored XSS with Blog entries (Insecure defaults)

Should you act?

Critical, preconditions apply

Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
• EPSS 0.5%, percentile 43: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 43% of all scored CVEs (low). EPSS is a probability, not a verdict.
• Needs an account (low (any account)). Exposure depends on who can log in.
• Only applies if your dependency tree includes com.liferay.portal:release.portal.bom (Maven) < 7.4.3.13, fixed in 7.4.3.13; com.liferay.portal:release.dxp.bom (Maven) >= 7.4.0, < 7.4.13.u9, fixed in 7.4.13.u9; com.liferay.portal:release.dxp.bom (Maven) >= 7.3.0, < 7.3.10.u4, fixed in 7.3.10.u4; com.liferay.portal:release.dxp.bom (Maven) < 7.2.10.fp19, fixed in 7.2.10.fp19. Check your lockfile, including transitive dependencies.

What it is

In Liferay Portal 7.2.0 through 7.4.3.12, and older unsupported versions, and Liferay DXP 7.4 before update 9, 7.3 before update 4, 7.2 before fix pack 19, and older unsupported versions, the default configuration does not sanitize blog entries of JavaScript, which allows remote authenticated users to inject arbitrary web script or HTML (XSS) via a crafted payload injected into a blog entry’s content text field.
