CVE-2026-9261: CWE-327: Use of a Broken or Risky Cryptographic Algorithm in Canon Inc. EOS Network Setting Tool for Windows
Use of weak SSH cryptographic algorithms in Canon EOS Network Setting Tool Version 1.5.0 or earlier
AI Analysis
Technical Summary
This vulnerability (CVE-2026-9261) affects Canon EOS Network Setting Tool for Windows versions up to and including 1.5.0. It involves the use of weak or broken SSH cryptographic algorithms, classified under CWE-327. The weakness in cryptographic algorithm usage could lead to high impact on confidentiality and integrity of data transmitted via SSH connections. No official patch or remediation level has been provided by Canon at the time of this report.
Potential Impact
The use of weak SSH cryptographic algorithms can allow attackers to potentially decrypt or tamper with data transmitted between the tool and network devices, compromising confidentiality and integrity. The CVSS 4.0 vector indicates network attack vector, high attack complexity, no privileges required, user interaction required, and high impact on confidentiality and integrity. There is no known exploit in the wild currently.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, users should monitor Canon's advisories for updates. Until a fix is available, minimizing use of affected versions or restricting network access to trusted environments may reduce risk.
