Title

Weaver E-cology 8.0 / 9.0 SQL Injection via HrmCareerApplyPerView.jsp

Summary

Weaver (Fanwei) E-cology 8.0 and 9.0 contains a SQL injection vulnerability in the HrmCareerApplyPerView.jsp endpoint that allows unauthenticated remote attackers to extract arbitrary data from the backend database by manipulating the id GET parameter. Attackers can send a single crafted GET request with UNION-based injection payloads through the unsanitized id parameter to retrieve arbitrary data from the Microsoft SQL Server backend. This vulnerability is potentially remediated in software version 10.53 or 10.54. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18 (UTC).

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
