Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations for logical access to system resources, directly preventing unauthorized forced browsing to sensitive product data and settings via crafted HTTP requests.

SC-7 Boundary Protection partial match

prevent

Monitors and controls communications at system boundaries, blocking remote attackers' crafted HTTP requests to vulnerable endpoints on the exposed web interface.

SI-10 Information Input Validation partial match

prevent

Validates information inputs such as HTTP requests, mitigating specially crafted requests that exploit the forced browsing vulnerability.

Deeper analysisAI

CVE-2025-26689 is a Direct request ('Forced Browsing') vulnerability, classified under CWE-425, affecting all versions of the CHOCO TEI WATCHER mini (IB-MCT001) device. This flaw enables unauthorized access to internal product functions through specially crafted HTTP requests, potentially exposing sensitive data or allowing unauthorized modifications.

The vulnerability can be exploited by any remote attacker over the network (AV:N) with low attack complexity (AC:L), no privileges (PR:N), and no user interaction (UI:N), earning a CVSS v3.1 base score of 9.8 (C:H/I:H/A:H). Successful exploitation allows the attacker to obtain or delete product data and alter product settings, compromising confidentiality, integrity, and availability.

Advisories from JVN (JVNVU#91154745), CISA (ICS-A-25-084-04), manufacturer Inaba Denki Sangyo (chocomini_vulnerability.pdf), and Nozomi Networks detail the issue in the context of production line monitoring cameras. These references address risks such as remote surveillance and interference with stoppage recording functions.

The Nozomi Networks analysis highlights that vulnerabilities like this remain unpatched in deployed production line cameras, increasing exposure to remote attacks.
