Security readout for executives and security teams
Plain-English summary
CVE-2015-10027 affects hydrian TTRSS-Auth-LDAP, an LDAP authentication plugin. A username handling flaw can allow LDAP injection, potentially affecting confidentiality, integrity, and availability at a limited level. The documented fix is upgrading to version 2.0b1 or applying the referenced patch.
Executive priority
Treat this as a moderate-priority authentication component issue. It is not documented as actively exploited, but affected systems should be upgraded because authentication flaws can become higher-impact when combined with weak network boundaries or reused credentials.
Technical view
The vulnerability is CWE-90 LDAP injection in the Username Handler of hydrian TTRSS-Auth-LDAP. The CVSS 3.1 score is 5.5 with adjacent-network attack vector, low complexity, low privileges required, no user interaction, and low impact across confidentiality, integrity, and availability.
Likely exposure
Exposure is likely limited to environments running hydrian TTRSS-Auth-LDAP, especially older versions before 2.0b1. The source bundle does not identify exact vulnerable version ranges beyond recommending the 2.0b1 upgrade.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. CVSS indicates exploitation requires adjacent network access and low privileges, which reduces broad internet-scale urgency but still matters for shared networks and authenticated environments.
Researcher notes
Evidence is thin on affected version boundaries and vulnerable function details. The strongest source-grounded facts are CWE-90, Username Handler involvement, CVSS 5.5, and remediation via release 2.0b1 or commit a7f7a5a82d9202a5c40d606a5c519ba61b224eb8.
Mitigation direction
- Upgrade hydrian TTRSS-Auth-LDAP to version 2.0b1.
- Verify patch a7f7a5a82d9202a5c40d606a5c519ba61b224eb8 is present.
- Prioritize systems where LDAP authentication is reachable from shared networks.
- Check GitHub and VulDB for any newer vendor guidance.
- Retire or isolate unmaintained plugin deployments if upgrade is not possible.
Validation and detection
- Inventory TT-RSS deployments using hydrian TTRSS-Auth-LDAP.
- Confirm installed plugin version is 2.0b1 or later.
- Review deployed code for the referenced patch commit.
- Validate LDAP username handling in a controlled test environment.
- Check logs for unusual authentication failures or LDAP query errors.

Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')
Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
