This flaw, detailed in ESET's security bulletin ca8972, allows an attacker to disrupt the availability of systems running the affected software. Specifically, Endpoint Antivirus versions prior to 12.0.14.0, 12.1.2.0, 12.2.9.0, 13.0.5.0, 13.1.5.0, and 13.2.3.0 are impacted, alongside Server Security versions before 12.0.292.0, 12.1.407.0, 12.2.73.0, 13.0.36.0, 13.1.118.0, and 13.2.53.0. The advisory, published on July 16, 2026, urges users to apply available patches to prevent potential service interruptions. The specific mechanism for triggering the denial of service is not publicly detailed, but its impact threatens the stability and operational integrity of protected endpoints and servers.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003cp\u003eThe provided source describes a vulnerability that allows an attacker to cause a denial of service (DoS) in ESET products. However, it does not specify the steps or methods an attacker would use to trigger this DoS, nor does it detail any observed exploitation scenarios or multi-stage attack chains. Therefore, a specific attack chain cannot be constructed from the available information.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-6424 leads to a denial of service on systems running vulnerable ESET Endpoint Antivirus and Server Security products. While the exact attack vector is not specified, an attacker can leverage this vulnerability to disrupt the normal operation of these security solutions, potentially rendering endpoints and servers unprotected or causing system instability. This could lead to a loss of availability for critical business functions reliant on these systems, creating operational disruptions and a temporary degradation of an organization's security posture. The scope of affected systems includes various ESET product lines, emphasizing the broad potential for disruption across different environments.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePatch CVE-2026-6424 immediately by upgrading ESET Endpoint Antivirus and Server Security products to the versions specified in ESET security bulletin ca8972.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-07-16T12:58:41Z","date_published":"2026-07-16T12:58:41Z","id":"https://feed.craftedsignal.io/briefs/2026-07-eset-dos/","summary":"A vulnerability, identified as CVE-2026-6424, has been discovered in various ESET Endpoint Antivirus and Server Security product versions, allowing an attacker to cause a denial of service, impacting the availability of the affected systems.","title":"Denial-of-Service Vulnerability Affects ESET Endpoint Antivirus and Server Security Products (CVE-2026-6424)","url":"https://feed.craftedsignal.io/briefs/2026-07-eset-dos/"}],"language":"en","title":"CraftedSignal Threat Feed - Endpoint Antivirus 13.1.x","version":"https://jsonfeed.org/version/1.1"}
