Open Information Security Foundation Suricata prior to version 4.1.3 is affected by: Denial of Service - TCP/HTTP detection bypass. The impact is: An attacker can evade a signature detection with a specialy formed sequence of network packets. The component is: detect.c (https://github.com/OISF/suricata/pull/3625/commits/d8634daf74c882356659addb65fb142b738a186b). The attack vector is: An attacker can trigger the vulnerability by a specifically crafted network TCP session. The fixed version is: 4.1.3.

Security readout for executives and security teams

Plain-English summary

Suricata versions before 4.1.3 could miss certain TCP/HTTP traffic patterns. This matters because Suricata is often used to detect network attacks; bypass weakens visibility rather than directly compromising a host. The provided sources name 4.1.3 as the fixed version.

Executive priority

Address during the next security maintenance cycle, sooner for sensors protecting critical or internet-facing environments. The issue weakens detection coverage, so the business risk is reduced visibility into attacks rather than direct system takeover.

Technical view

CVE-2019-1010279 affects Open Information Security Foundation Suricata before 4.1.3. The reported component is detect.c. A specially formed TCP session can cause TCP/HTTP signature detection bypass, described as a denial-of-service impact against detection capability. No CVSS score, CWE, or detailed affected platform list is provided.

Likely exposure

Organizations running Suricata sensors, appliances, or packages below version 4.1.3 are potentially exposed. Exposure is most relevant where Suricata is relied on for TCP/HTTP attack detection, alerting, or blocking decisions. The source bundle does not identify specific distributions, managed services, or downstream products.

Exploitation context

The sources describe a crafted network TCP session as the attack vector. They do not provide evidence of active exploitation, public weaponization, or CISA KEV listing. Treat exploitation status as unconfirmed based on the supplied evidence.

Researcher notes

Evidence is limited to the CVE record, OISF Redmine issue, GitHub pull request, and fix commit. The root issue is in detection logic, but the bundle does not include CVSS scoring, exploitation reports, or operational workaround details.

Mitigation direction

  • Upgrade Suricata to version 4.1.3 or later.
  • Check OISF/vendor guidance for deployment-specific update instructions.
  • Prioritize internet-facing and high-value network monitoring points.
  • Use alternate telemetry while affected sensors are being updated.
  • Document any accepted risk for sensors that cannot be upgraded.

Validation and detection

  • Inventory all Suricata deployments and recorded package versions.
  • Confirm every in-scope sensor runs Suricata 4.1.3 or later.
  • Review detection regression coverage for TCP/HTTP inspection paths.
  • Check security monitoring gaps during the affected version window.
  • Verify vendor or appliance firmware includes the Suricata fix.
