HP Fixes Vulnerabilities in ArcSight Products

HP has released software updates to address several vulnerabilities affecting ArcSight Enterprise Security Manager (ESM) and ArcSight Logger, products that are part of the company’s enterprise security portfolio.

An advisory published by the CERT Coordination Center at Carnegie Mellon University on Tuesday shows that a total of five security holes have been uncovered by Poland-based security researcher Julian Horoszkiewicz in the two HP ArcSight products.

One of the vulnerabilities affecting ArcSight Logger can be exploited by a remote, authenticated attacker to upload arbitrary files to the affected system. A malicious actor might be able to execute scripts on the server with the application’s privileges. Uploading arbitrary files is possible because the product’s configuration import feature does not sanitize file names, CERT said.

Another Logger issue can be exploited by an authenticated attacker to modify sources and parsers. The weakness exists because all users are allowed to access certain configuration features, such as input, search, and content management.

Horoszkiewicz has also found that the XML parser in Logger’s content import section is vulnerable to XML External Entity Injection attacks. A malicious actor could leverage the bug to execute arbitrary scripts on the server.

The HP ArcSight vulnerabilities identified by the researcher are a cross-site scripting (XSS) flaw that could allow an attacker to disrupt or modify rules and resources on the system, and a cross-site request forgery (CSRF) that can be exploited to modify data on the system. Since these types of vulnerabilities are exploited by tricking the victim into clicking on a maliciously crafted link, the extent of the damage that an attacker can cause depends on the privileges of the targeted user.

HP says the vulnerabilities impact ArcSight ESM prior to version 6.8c, and ArcSight Logger prior to version 6.0P1.

CERT’s advisory shows that CVE identifiers are pending for each of the flaws. However, HP’s own advisory reveals that an identifier, CVE-2014-7885, has been assigned to multiple vulnerabilities in HP ArcSight ESM, and a second identifier, CVE-2014-7884, has been assigned to multiple flaws in HP ArcSight Logger.

Horoszkiewicz has uploaded a proof-of-concept for the ArcSight Logger file upload vulnerability to Offensive Security’s Exploit Database. The researcher said he had sent a vulnerability report to HP in late August 2014, and new versions containing the fix were released on January 21, 2015.
