Jun 26, 2018Delta Industrial Automation COMMGR from Delta Electronics versions 1.08 and prior with accompanying PLC Simulators (DVPSimulator EH2, EH3, ES2, SE, SS2 and AHSICVE-2018-10594 · Other software · ICS-CERT · reported by ics-cert@hq.dhs.govCritical 9.8
Delta Industrial Automation COMMGR from Delta Electronics versions 1.08 and prior with accompanying PLC Simulators (DVPSimulator EH2, EH3, ES2, SE, SS2 and AHSIM_5x0, AHSIM_5x1) utilize a fixed-length stack buffer where an unverified length value can be read from the network packets via a specific network port, causing the buffer to be overwritten. This may allow remote code execution, cause the application to crash, or result in a denial-of-service condition in the application server.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
