Canon EOS Network Setting Tool Cryptographic Flaws

Information disclosure in Canon EOS Network Setting Tool version 1.5.0 and earlier stems from improper SSH host key validation (CWE-295), allowing network-positioned attackers to impersonate legitimate SSH endpoints and harvest credentials or configuration data transmitted by the tool. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:P, VC:H) indicates remote exploitation requiring user interaction with high confidentiality impact but no integrity or availability effects. There is no public exploit identified at time of analysis, and the issue is not on the CISA KEV list.

Improper TLS certificate validation in Canon EOS Network Setting Tool version 1.5.0 and earlier allows network-positioned attackers to intercept communications between the tool and Canon servers via man-in-the-middle attacks. The flaw enables disclosure of sensitive information transmitted during camera network configuration, though no public exploit identified at time of analysis. CVSS 4.0 score of 7.1 reflects high confidentiality impact but requires user interaction (UI:P) to be successful.

Information disclosure in Canon EOS Network Setting Tool version 1.5.0 and earlier stems from an insecure default FTP configuration that transmits credentials and image data in cleartext over the network. Remote attackers positioned on the network path can intercept the unencrypted FTP traffic to capture authentication material and uploaded photographs. No public exploit identified at time of analysis, but the vulnerability is published with a Canon PSIRT advisory and CVSS 4.0 base score of 7.1.

Hard-coded cryptographic keys embedded in Canon EOS Network Setting Tool version 1.5.0 and earlier expose static decryption material to any local system user, enabling unauthorized decryption of protected network traffic or configuration data exchanged between the tool and Canon EOS cameras. The flaw is CWE-321 (Use of Hard-coded Cryptographic Key) and is classified as an information disclosure vulnerability with high confidentiality impact, bounded by the requirement for local system access. No public exploit has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog.
