CVE-2026-44858 | Authenticated Stack-Based Buffer Overflow in PAPI Services

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.

Base score Version Severity Vector Exploitability Impact Score source
7.2 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
