Liferay DXP Vulnerable to Denial-of-service (DoS) in the Multi-Factor Authentication Module
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2021-29041 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Denial-of-service (DoS) vulnerability in the Multi-Factor Authentication module in Liferay DXP 7.3 before fix pack 1 allows remote authenticated attackers to prevent any user from authenticating by (1) enabling Time-based One-time password (TOTP) on behalf of the other user or (2) modifying the other user's TOTP shared secret.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay.portal:release.dxp.bom, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.liferay.portal:release.dxp.bom to 7.3.10.fp1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-29041 is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2021-29041 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2021-29041. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
