Title

SAP Process Integration权限许可和访问控制问题漏洞（CNVD-2021-36675）

Description

SAP Process Integration是德国SAP公司提供的一种中间件，可使SAP与公司中的非SAP应用程序或公司外部的系统进行无缝集成。 SAP Process Integration 7.10、7.11、7.20、7.30、7.31、7.40和7.50版本中存在权限许可和访问控制问题漏洞，该漏洞源于Integration Builder Framework未能充分验证从本地源上传的XML文档。攻击者可以创建恶意XML，当应用程序上载和解析该XML时，可能会由于消耗大量系统内存而导致拒绝服务情况，从而严重影响系统可用性。

CVE-2021-27617 (GCVE-0-2021-27617)

Vulnerability from cvelistv5 – Published: 2021-05-11 14:19 – Updated: 2024-08-03 21:26

Summary

The Integration Builder Framework of SAP Process Integration versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently validate an XML document uploaded from local source. An attacker can craft a malicious XML which when uploaded and parsed by the application, could lead to Denial-of-service conditions due to consumption of a large amount of system memory, thus highly impacting system availability.

Severity

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.
