Security readout for executives and security teams
Plain-English summary
CVE-2015-10116 is a cross-site request forgery issue in the WordPress RealFaviconGenerator Favicon Plugin. A remote attacker could cause an unintended favicon installation action if conditions for CSRF are met. The published impact is integrity-only, not data theft or service outage. Version 1.2.13 fixes the issue.
Executive priority
Schedule remediation in the normal vulnerability cycle, sooner for externally exposed WordPress sites. The issue is not described as actively exploited, but it affects administrative integrity and has a named fixed version, making upgrade the practical path.
Technical view
The vulnerable code is the install_new_favicon function in admin/class-favicon-by-realfavicongenerator-admin.php for plugin versions 1.2.0 through 1.2.12. The weakness is CWE-352. The CVSS v2 score is 5.0 with network attack vector, low complexity, no attacker authentication, partial integrity impact, and no confidentiality or availability impact.
Likely exposure
Exposure is limited to WordPress sites running RealFaviconGenerator Favicon Plugin versions 1.2.0 through 1.2.12. Sites not using this plugin, or already upgraded to 1.2.13 or later, are not indicated as affected by the provided sources.
Exploitation context
The bundle says the attack can be initiated remotely, but KEV is false and no provided source confirms active in-the-wild exploitation. Treat this as a credible medium-risk WordPress plugin issue, especially where admin users can be targeted through CSRF conditions.
Researcher notes
The sources identify the vulnerable function and patch but do not provide detailed exploit conditions beyond CSRF and remote initiation. Do not assume confidentiality impact, availability impact, or confirmed exploitation from the provided evidence.
Mitigation direction
- Upgrade RealFaviconGenerator Favicon Plugin to version 1.2.13 or later.
- Confirm the patched commit 949a1ae is included in the deployed plugin version.
- Review vendor guidance before applying any workaround not named in sources.
- Prioritize affected public WordPress sites with active administrative use.
Validation and detection
- Inventory WordPress sites for the RealFaviconGenerator Favicon Plugin.
- Verify installed plugin versions are not 1.2.0 through 1.2.12.
- Check that version 1.2.13 or later is deployed after remediation.
- Record whether the site is public-facing and actively administered.
