CVE-2025-43798
MEDIUMCVE-2025-43798 is a medium-severity (CVSS 6.5) CWE-304 vulnerability in liferay digital experience platform. O3 Security detects and blocks CVE-2025-43798 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.
Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92 and 7.3 GA through update 35 allows a time-based one-time password (TOTP) to be used multiple times during…
Description
Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92 and 7.3 GA through update 35 allows a time-based one-time password (TOTP) to be used multiple times during the validity period, which allows attackers with access to a user’s TOTP to authenticate as the user.

Vendor / applianceDetect
Inventory every liferay digital experience platform deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the liferay digital experience platform security patch or hotfix for CVE-2025-43798 on the affected version, following the vendor advisory for your exact build.
Workarounds
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2025-43798 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2025-43798. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-43798 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2025-43798 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
