HP Fixes Vulnerabilities in ArcSight Products
Posted on March 18, 2015 by Kara Dunlap in Security
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.

Numerous Vulnerabilities Found in Zenoss Core Management Platform
Posted on December 8, 2014 by Kara Dunlap in Security
Researchers have uncovered a total of 20 security holes in Zenoss Core, the free, open-source version of the application, server, and network management platform Zenoss.
According to an advisory published on Friday by the CERT Coordination Center at Carnegie Mellon University (CERT/CC), the vulnerabilities were identified and reported by Ryan Koppenhaver and Andy Schmitz of Matasano Security.
One of the most serious flaws is CVE-2014-6261, which can be exploited by a remote attacker to execute arbitrary code.
“An attacker who is able to get a victim to visit an attacker-controlled website while logged in to the Zenoss interface can execute arbitrary code on the Zenoss installation. Additionally, an attacker who is able to perform a man-in-the-middle attack between the Zenoss installation and Zenoss’ corporate ‘callhome’ server – or control the ‘callhome’ server – can execute arbitrary code on the Zenoss installation,” reads Zenoss’ description of the vulnerability.
Another serious vulnerability (CVE-2014-9246) is caused by the fact that sessions don’t expire. In order to exploit the bug, an attacker needs to obtain a targeted user’s session ID and copy it to his own computer. When the victim logs in, the attacker will be logged in as that user.
Researchers have also identified cross-site request forgery (CSRF), persistent cross-site scripting (XSS), information disclosure, open redirect, authorization bypass, and denial-of-service (DoS) vulnerabilities. In addition, the experts discovered multiple issues related to passwords, including the lack of password complexity requirements, a weak hashing algorithm, and the storing of passwords in plaintext in the session database.
These vulnerabilities have been assigned the following CVE identifiers: CVE-2014-6253, CVE-2014-6254, CVE-2014-9245, CVE-2014-6255, CVE-2014-6256, CVE-2014-9247, CVE-2014-9248, CVE-2014-6257, CVE-2014-9249, CVE-2014-6258, CVE-2014-6260, CVE-2014-9251, CVE-2014-6259, CVE-2014-6262 and CVE-2014-9252.
The vulnerabilities affect Zenoss Core 4.2.4. Two of the flaws, the session expiration bug and an open redirect in the login form (CVE-2014-6255 and CVE-2014-9246), have been addressed by Zenoss with the release of the latest Zenoss Core 4.2.5 service pack, CERT/CC said. The company is internally tracking the other bugs and plans of fixing them in a future maintenance release of Zenoss Core 5, which is currently in beta.
Zenoss does not plan on addressing CVE-2014-9250, which can be exploited by an attacker to obtain a user’s username and password by retrieving the authentication cookie. The company advises customers who want to use cookie-based authentication to ensure their installations operate over SSL/HTTPS.
