Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Monday's brief is dominated by GeoVision vulnerabilities affecting GV-VMS video management software and LPC2011/LPC2211 devices, alongside critical flaws in Totolink WA300 routers and LG GV-IP Device Utility. The brief includes 7 critical CVEs (up 250% from 2) and 36 high-priority CVEs (down 64% from 100). Notable disclosures include CVE-2026-42369 (CVSS 10) and CVE-2026-42370 in GeoVision GV-VMS, plus CVE-2026-7719 in Totolink WA300. Network edge devices, video surveillance platforms, and IP camera utilities represent the primary attack surface, with 9 vulnerabilities under active exploitation across Microsoft Defender, D-Link, SimpleHelp, and ConnectWise products. Zero patches are currently available across the disclosed set, requiring compensating controls and network segmentation.

  • GeoVision accounts for five of seven critical CVEs, including a maximum-severity CVSS 10 flaw in GV-VMS
  • Critical CVEs increased 250% to 7 compared to 2 the prior day
  • High-priority CVEs decreased 64% to 36 from 100 the prior day
  • Network and surveillance infrastructure dominates with Totolink WA300, LG GV-IP, and GeoVision devices exposed
  • Patch availability stands at 0%, requiring network segmentation and access controls as interim mitigations
  • 9 vulnerabilities show active exploitation across Microsoft Defender, SimpleHelp, ConnectWise ScreenConnect, and Linux Kernel

Immediate action: Prioritize isolation and access restriction for GeoVision GV-VMS deployments and LPC2011/LPC2211 devices, along with Totolink WA300 routers and LG GV-IP Device Utility installations. With 0% patch availability, defenders should restrict management interfaces to trusted networks, monitor for exploitation attempts against actively exploited products including SimpleHelp and ConnectWise ScreenConnect, and prepare patch deployment workflows for vendor releases.

How to read this brief

CVSS score (e.g. 9.1) — severity from 0–10. Red marks critical (9+), orange high (7–8.9).

Exploitability — how hard the flaw is to attack, read from the CVSS vector:

  • Network / Adjacent / Local / Physical — how close an attacker must get. Network means reachable over the internet.
  • No / Low / High privileges — the access they need first. No privileges means no login required.
  • No interaction / User interaction — whether a victim has to do something (open a file, click a link). No interaction means fully automatable.

The lower the bar on all three, the easier to exploit at scale — “Network · No privileges · No interaction” is the worst case: hit from anywhere, no credentials, no victim action.

Actively exploited — confirmed under attack in the wild (CISA’s Known Exploited Vulnerabilities catalog). Prioritize these regardless of score.

EPSS · Nth percentile — FIRST.org’s estimated chance a flaw is exploited within 30 days. We flag it only in the top 10% — a statistical signal it’s unusually likely to be targeted, separate from whether attacks are confirmed.
