Severity

6.9 (Medium) - CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:C/C:H/I:L/A:L

Summary

The vulnerability, if exploited, could allow an authenticated miscreant (with privilege of "aaConfigTools") to tamper with App Objects' help files and persist a cross-site scripting (XSS) injection that when executed by a victim user, can result in horizontal or vertical escalation of privileges. The vulnerability can only be exploited during config-time operations within the IDE component of Application Server. Run-time components and operations are not affected.

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.
