AI Analysis

Impact

An unauthenticated attacker can trigger a stack-based buffer overflow by sending specially crafted cookies when the SafeEnhancement feature is active in Advantech ADAM‑3600 devices, allowing arbitrary code execution. This flaw arises from improper input validation in the Cookie parsing logic, a classic stack buffer overflow (CWE‑121). The vulnerability can compromise the confidentiality, integrity, and availability of the affected device, giving an attacker full control over the system without requiring any prior authentication.

Affected Systems

The check identifies Advantech ADAM‑3600 as the affected product, but no specific firmware or software version ranges are listed. Administrators should verify whether their installations match the conditions described in the vendor’s security advisory.

Risk and Exploitability

The CVSS score of 9.2 indicates critical severity, and the EPSS score remains below 1 %, suggesting exploitation is currently unlikely but possible once a public exploit is crafted. The vulnerability is not listed in CISA’s KEV catalog. Attackers could exploit the flaw remotely via crafted cookie traffic when the SafeEnhancement feature is enabled, bypassing authentication controls and executing arbitrary code.

Remediation

Vendor Solution

Advantech has released a security update to address these vulnerabilities. Users and administrators of affected product versions are advised to update to the latest version immediately.


OpenCVE Recommended Actions

  • Apply the Advantech security update immediately to mitigate the stack buffer overflow.
  • Disable the SafeEnhancement feature until a patch can be applied, thereby removing the execution vector the flaw relies on.
  • Segment or firewall the device from external networks to limit the attack surface if a patch cannot be applied promptly.
