DescriptionCVE.org

A security vulnerability has been detected in Jinher OA 1.0. This affects an unknown function of the file nextselectplan.aspx. Such manipulation of the argument httpOID leads to sql injection. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

SQL injection in Jinher OA 1.0 allows remote unauthenticated attackers to manipulate the httpOID parameter of nextselectplan.aspx to inject arbitrary SQL statements. Publicly available exploit code exists per VulDB disclosure, and the vendor did not respond to coordinated disclosure attempts, increasing the window of exposure. …

Vulnerability AssessmentAI

Exploitation No special conditions - remote unauthenticated exploitation against default configurations of Jinher OA 1.0, provided the nextselectplan.aspx endpoint is network-reachable to the attacker. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Multiple signals point to a moderate but credible risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A remote attacker scans for internet-exposed Jinher OA instances and issues an HTTP request to /nextselectplan.aspx with a crafted httpOID parameter (for example, a UNION-based payload) to extract usernames, password hashes, or business records from the backing database. Because the publicly available exploit referenced on GitHub provides a working payload template, weaponization effort is minimal and the attacker can iterate quickly toward full database enumeration.
Remediation No vendor-released patch identified at time of analysis, as VulDB reports the vendor did not respond to disclosure. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

24 hours: Execute asset inventory for all Jinher OA 1.0 instances; remove internet-facing deployments or isolate behind network controls. …
