CVE-2019-20383: ABBYY network license server in ABBYY FineReader 15 before Release 4 (aka 15.0.112.2130) allows escalation...

Security readout for executives and security teams

This is a local privilege escalation issue in ABBYY FineReader 15's network license server before Release 4. A user who already has local access to an affected machine could potentially gain higher privileges by abusing file handling and symbolic links. It is not described as remotely exploitable in the provided sources. Exposure is most likely on endpoints or servers running ABBYY FineReader 15 with the network license server component installed, especially builds earlier than Release 4. The provided affected-product metadata is incomplete, so teams should validate actual installed ABBYY components rather than relying only on CPE matching. Treat this as a targeted hygiene item, not an internet-wide emergency. Prioritize patching where ABBYY licensing components run on shared workstations, terminal servers, or other systems with multiple local users. Risk rises if lower-privileged users can access those hosts. Mitigation focus: Upgrade ABBYY FineReader 15 to Release 4 or later, following ABBYY guidance.; Remove or disable the network license server where it is not required.; Restrict local interactive access to systems running the license server..
