Security readout for executives and security teams
Plain-English summary
CVE-2015-10105 affects the WordPress IP Blacklist Cloud Plugin through version 3.42. A filename handling flaw in CSV import can allow path traversal, meaning an authenticated remote user may be able to reach files outside the intended import path. The supplied sources identify version 3.43 as the fix.
Executive priority
Prioritize remediation during the next WordPress maintenance window, sooner for internet-facing sites with multiple admin users. The issue has a clear fixed version and a meaningful file-access risk, but the provided evidence does not show active exploitation.
Technical view
The issue is CWE-22 path traversal in valid_js_identifier within ip_blacklist_cloud.php, tied to CSV File Import filename handling. The provided CVSS v2 vector is AV:N/AC:L/Au:S/C:P/I:P/A:P, indicating network reachability, low complexity, required authentication, and partial confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites running IP Blacklist Cloud Plugin versions 3.0 through 3.42. No CPEs are supplied, so validation depends on WordPress plugin inventory and version checks. Risk is higher where CSV import functionality is available to users beyond tightly trusted administrators.
Exploitation context
The source bundle says remote initiation is possible and authentication is required by the CVSS vector. It does not provide evidence of active exploitation, public weaponization, or KEV listing. Treat this as a credible patch-management issue rather than a confirmed active campaign.
Researcher notes
Evidence is mostly from VulDB, CVE records, and the GitHub patch/release. The affected component and function are named, but the bundle does not include exploit details, observed attacks, or broader ecosystem telemetry. Validate authorization requirements directly in the affected plugin version if risk scoring needs refinement.
Mitigation direction
- Upgrade IP Blacklist Cloud Plugin to version 3.43 or later.
- Confirm the patch commit is present if using a mirrored or customized plugin copy.
- Restrict CSV import capability to trusted administrators until upgrade is complete.
- Review vendor or project guidance before applying any non-upgrade workaround.
Validation and detection
- Inventory WordPress sites for IP Blacklist Cloud Plugin installations.
- Flag installed versions 3.0 through 3.42 as affected.
- Verify version 3.43 release or patch commit deployment.
- Review access to CSV import functionality and relevant administrative users.
- Check logs for unusual CSV import or filename-related activity.
