Last modified

CVE-2026-44859 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. Stack-based buffer overflow vulnerabilities exist in several underlying management service components accessed through the command-line interface of the AOS-8 and AOS-10 Operating Systems. An authenticated attacker with administrative privileges could exploit these vulnerabilities by sending specially crafted requests to the affected services. EPSS estimates a 0.36% chance of exploitation in the next 30 days.

Description

Stack-based buffer overflow vulnerabilities exist in several underlying management service components accessed through the command-line interface of the AOS-8 and AOS-10 Operating Systems. An authenticated attacker with administrative privileges could exploit these vulnerabilities by sending specially crafted requests to the affected services. Successful exploitation could allow the attacker to execute arbitrary code with elevated privileges on the underlying operating system.
