CVE-2024-5682: User Enumeration in Yordam Information Technology's Yordam Library Automation System
Improper Restriction of Excessive Authentication Attempts vulnerability in Yordam Information Technology Yordam Library Automation System allows Interface Manipulation.
This issue affects Yordam Library Automation System: before 20.1.
Security readout for executives and security teams
Plain-English summary
CVE-2024-5682 is a user-enumeration weakness in Yordam Library Automation System before version 20.1. An unauthenticated network attacker may be able to infer valid users through authentication behavior. This mainly raises account-targeting risk rather than direct system takeover.
Executive priority
Treat this as a moderate-priority identity exposure issue. It does not indicate takeover by itself, but it can help attackers build valid user lists for phishing, password attacks, or targeted account abuse.
Technical view
The CVE describes CWE-307, improper restriction of excessive authentication attempts, allowing interface manipulation. CVSS 4.0 is 6.9 with network access, low attack complexity, no privileges, and no user interaction. Reported impact is limited confidentiality impact, including possible exposure useful for user enumeration.
Likely exposure
Exposure is likely limited to organizations running Yordam Library Automation System versions before 20.1, especially internet-accessible library portals or authentication interfaces. The source metadata is sparse and lists default status as unaffected outside the stated affected range.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not marked in KEV. The issue is remotely reachable and unauthenticated, but published evidence only supports user-enumeration risk, not code execution or full compromise.
Researcher notes
Evidence is limited to CVE metadata and Turkish government advisory references. The USOM link is marked broken in the bundle. Avoid assuming exploit availability, affected deployments beyond Yordam Library Automation System, or precise fixes beyond the before-20.1 version boundary.
Mitigation direction
Identify any Yordam Library Automation System deployments and their exposed authentication interfaces.
Move off versions before 20.1 if vendor guidance confirms the fixed release path.
Review vendor or Turkish government advisory updates for official remediation details.
Apply rate limiting, lockout controls, and uniform authentication responses where configurable.
Restrict administrative or staff login interfaces from public internet exposure where possible.
Validation and detection
Confirm whether deployed Yordam Library Automation System versions are before 20.1.
Check external exposure of login, account recovery, and library user interfaces.
Review authentication logs for repeated failed attempts or systematic username probing.
Verify login responses do not reveal whether an account exists.
Document compensating controls if immediate upgrade is not possible.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
