SolarView Compact contains a cross-site scripting vulnerability in Image Management. If this vulnerability is exploited, an arbitrary OS command may be executed by an attacker who can log in to the product.
AnalysisAI
Cross-site scripting in the Image Management component of Contec SolarView Compact (models sv-cpt-mc310 and sv-cpt-mc310f) enables authenticated attackers to inject malicious script that can trigger arbitrary OS command execution on the underlying device. Reported by JPCERT/CC (JVNVU97753461) with a Contec vendor advisory, the vulnerability chains CWE-79 XSS with a command injection pathway, making it more dangerous than its CVSS 4.0 score of 5.1 suggests. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold valid login credentials for the SolarView Compact web interface - the vendor description explicitly states 'an attacker who can log in to the product.' The vulnerable feature is Image Management specifically; access to that section of the interface is a prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS 4.0 base score of 5.1 (AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N) materially understates the real-world risk on two counts: first, the PR:N metric directly conflicts with the vendor description stating 'an attacker who can log in to the product,' implying at minimum PR:L; second, the VC:N/VI:N/VA:N assignment ignores the explicitly stated arbitrary OS command execution impact on the device itself, which should yield high vulnerable-component impact scores. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patch described in Contec's security advisory (https://www.contec.com/api/downloadlogger?download=/-/media/Contec/support/security-info/2026/contec_security_sv_26091000_en.pdf). … Detailed patch versions, workarounds, and compensating controls in full report. |
