Security readout for executives and security teams
Plain-English summary
openitcockpit before 4.6.6 set a sensitive HTTPS session cookie without the Secure flag. That can let browsers send the cookie over an unencrypted HTTP request to the same site, risking limited session confidentiality exposure. The published severity is medium, not a system takeover finding.
Executive priority
Treat as a moderate web-session hygiene issue. Prioritize remediation during the next normal maintenance window, faster for externally reachable portals or environments with untrusted networks. It does not have supplied evidence of active exploitation or integrity/availability impact.
Technical view
CVE-2023-3520 is CWE-614 in it-novum/openitcockpit before 4.6.6. The CVSS 3.0 vector is AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N, score 4.3. The issue concerns missing Secure attribute protection on a sensitive session cookie.
Likely exposure
Exposure is limited to organizations running it-novum/openitcockpit versions prior to 4.6.6. Risk is higher where users can reach the same host over HTTP or where network paths are not fully trusted. The source bundle does not identify affected deployment modes beyond the product and version boundary.
Exploitation context
The source bundle does not report active exploitation, and the CVE is not listed as KEV. The CVSS vector indicates network reachability, low attack complexity, low privileges required, no user interaction, and low confidentiality impact only.
Researcher notes
Validation should focus on cookie attributes and version state, not exploit development. The available evidence is concise: CVE metadata, a huntr reference, and a vendor commit. No source in the bundle names broader affected products or exploitation in the wild.
Mitigation direction
- Upgrade openitcockpit to 4.6.6 or later where vendor-supported.
- Review the referenced vendor commit and huntr report for implementation context.
- Ensure sensitive session cookies are issued with the Secure attribute.
- Check vendor guidance before applying custom cookie-handling changes.
Validation and detection
- Inventory openitcockpit deployments and confirm whether versions are before 4.6.6.
- Inspect HTTPS session cookies and verify sensitive cookies include Secure.
- Confirm HTTP access paths do not receive sensitive session cookies.
- Run the relevant regression tests after upgrading or changing cookie configuration.

Sensitive Cookie in HTTPS Session Without 'Secure' Attribute
Sensitive Cookie in HTTPS Session Without 'Secure' Attribute represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
