CVE-2026-8987: CWE-122 Heap-based buffer overflow in Autel MaxiCharger Single
A heap-based buffer overflow vulnerability exists in Autel MaxiCharger Single firmware up to version V1.03.51 in the set_ap_param command via the /localcfg endpoint. This flaw requires authentication and allows an attacker to supply oversized input, potentially causing denial of service or arbitrary code execution. The vulnerability is critical with a CVSS score of 9.4. No patch or official remediation information is currently available.
AI Analysis
Technical Summary
CVE-2026-8987 is a heap-based buffer overflow vulnerability in the Autel MaxiCharger Single firmware through version V1.03.51. The issue occurs in the set_ap_param command handled by the /localcfg endpoint, where an authenticated attacker can provide input exceeding expected size limits. This can lead to denial of service and may allow arbitrary code execution. The vulnerability has a high severity rating (CVSS 9.4) and requires low attack complexity with no user interaction. No vendor advisory or patch information is currently available, and the product is not a cloud service.
Potential Impact
An authenticated attacker can exploit this vulnerability to cause a denial of service or potentially execute arbitrary code on the affected device. This could lead to device compromise or disruption of its normal operation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the /localcfg endpoint and limit authenticated user privileges to reduce exposure.
