Privilege escalation in ARC Informatique PcVue SCADA/HMI software (all versions prior to 17.0.0) arises because the encryption algorithm protecting user-account configuration in the built-in user directory is cryptographically inadequate (CWE-326). A local attacker with low privileges can decrypt or tamper with the stored account configuration and ultimately obtain privileged access to the PcVue application. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the vendor CVSS 4.0 base score is 8.4 (High).
Insecure credential storage in PcVue exposes built-in user account passwords to any local attacker with low-privileged filesystem access, across all versions prior to 17.0.0. The credentials are stored unprotected in the project's User directory, recoverable without elevated OS privileges. No public exploit code has been identified at time of analysis, but in OT/SCADA environments where PcVue is deployed, recovered credentials could enable unauthorized control of industrial processes.
A cleartext storage of sensitive information vulnerability exists in PcVue versions 8.10 through 15.2.3. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.
An insertion of sensitive information into log file vulnerability exists in PcVue versions 15 through 15.2.2. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
The affected device stores sensitive information in cleartext, which may allow an authenticated user to access session data stored in the OAuth database belonging to legitimate users. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
