Security readout for executives and security teams
Plain-English summary
rdiffweb versions before 2.4.6 could set a sensitive session cookie without the Secure attribute. That weakens session protection because browsers may send the cookie over non-HTTPS requests, increasing the chance of session exposure in certain network conditions.
Executive priority
Treat as a scheduled remediation item unless rdiffweb is used from untrusted or shared networks. It is not evidenced as actively exploited, but it affects session confidentiality and should not remain open.
Technical view
CVE-2022-3250 is CWE-614 in ikus060/rdiffweb before 2.4.6. The CVSS 3.0 score is 4.9 with adjacent-network attack vector, low complexity, low privileges, required user interaction, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to organizations running ikus060/rdiffweb versions prior to 2.4.6, especially where authenticated users access the service from networks an adjacent attacker could influence or observe.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. The risk depends on user interaction and network context, not a remote unauthenticated takeover path.
Researcher notes
Evidence is concise: the CVE description, CVSS vector, Huntr reference, and fixing commit. Sources do not provide exploit details, broad product impact, or operational mitigations beyond the version boundary and cookie-attribute correction.
Mitigation direction
- Upgrade rdiffweb to version 2.4.6 or later.
- Review the referenced vendor commit and release guidance.
- Confirm authenticated session cookies include the Secure attribute.
- Prioritize HTTPS-only access paths for rdiffweb deployments.
Validation and detection
- Inventory deployed rdiffweb versions and flag anything before 2.4.6.
- In a test login, inspect Set-Cookie attributes for Secure.
- Confirm no public route depends on insecure session-cookie behavior.
- Record compensating controls if upgrade cannot happen immediately.
