Improper Restriction of Excessive Authentication Attempts vulnerability in Akinsoft LimonDesk allows Authentication Bypass.
This issue affects LimonDesk: from s1.02.14 before v1.02.17.
Security readout for executives and security teams
Plain-English summary
Akinsoft LimonDesk has a high-severity OTP bypass issue. In affected versions, the system does not sufficiently restrict repeated authentication attempts, which can let an unauthenticated remote attacker bypass authentication. This could expose sensitive helpdesk data and allow limited integrity or availability impact.
Executive priority
Prioritize remediation for any internet-facing LimonDesk deployment. The issue is high severity because it may bypass OTP without credentials, creating direct risk to support data and operational workflows.
Technical view
CVE-2025-2416 is a CWE-307 excessive authentication attempts flaw in Akinsoft LimonDesk. The CVE states it affects LimonDesk from s1.02.14 before v1.02.17. CVSS 3.1 is 8.6 with network access, low complexity, no privileges, and no user interaction required.
Likely exposure
Exposure is limited to organizations running Akinsoft LimonDesk from s1.02.14 before v1.02.17. Risk is higher where the LimonDesk authentication or OTP flow is reachable from the internet or untrusted networks.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. The scoring indicates remote, unauthenticated, low-complexity exploitation is plausible, but no public exploit status is established in the bundle.
Researcher notes
Evidence is sparse beyond the CVE description, CVSS vector, affected version range, and government references. Treat v1.02.17 as the remediation boundary stated by the CVE, and avoid assuming broader product impact without vendor confirmation.
Mitigation direction
Upgrade affected LimonDesk deployments to v1.02.17 or later.
Check Akinsoft or national advisory guidance for vendor-specific remediation steps.
Restrict access to LimonDesk authentication surfaces where operationally feasible.
Monitor authentication logs for abnormal OTP retry patterns.
Validation and detection
Inventory LimonDesk deployments and record exact version numbers.
Confirm no deployment is from s1.02.14 before v1.02.17.
Review internet exposure for LimonDesk login and OTP endpoints.
Check authentication logs for excessive OTP attempts or unusual login success patterns.

Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
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.
