Security Bulletin: Due to the use of XStream, IBM Tivoli Netcool Configuration Manager is vulnerable to Denial of Service (DoS) attacks

Summary

XStream is used in ITNCM to serialize XML data and may be vulnerable to Denial of Service attacks (DoS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by causing a stackoverflow. This effect may support a denial of service attack (CVE-2022-40151,CVE-2022-40152,CVE-2022-40154,CVE-2022-40155,CVE-2022-40156) .

Vulnerability Details

CVEID:CVE-2022-40152
**DESCRIPTION:**XStream is vulnerable to a denial of service, caused by a stack-based buffer overflow. By sending a specially-crafted XML data, a remote authenticated attacker could exploit this vulnerability to causes the parser to crash, and results in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/236355 for the current score.
