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.
Network Vision Fixes Code Injection Vulnerability in IntraVUE Software
Posted on February 27, 2015 by Kara Dunlap in Security
Organizations that use the IntraVUE network visualization software from Network Vision are advised to update their installations as soon as possible because older versions of the solution are plagued by a critical vulnerability.
A code injection flaw (CVE-2015-0977) has been found in IntraVUE by Jürgen Bilberger from Daimler TSS GmbH, a security researcher who has discovered and reported vulnerabilities in several industrial control system (ICS) products over the past years.
According to an advisory from ICS-CERT, a remote, unauthenticated attacker can exploit the vulnerability to execute arbitrary operating system commands that could impact the availability, integrity, and confidentiality of affected servers.
This is a high-severity vulnerability with a CVSS base score of 10. Even an attacker with low skill could leverage the bug, but there is no evidence that an exploit is publicly available, ICS-CERT noted.
The security hole affects all Windows versions of IntraVUE prior to 2.3.0a14. The issue has been addressed with the release of IntraVUE 2.3.0a14 on February 9. In the meantime, Network Vision also released version 2.3.0a16, which brings some functionality improvements.
“It is recommended that the new version be applied as soon as possible. Users who have software support contracts with Network Vision can upgrade to the newest version at no cost,” reads the advisory from ICS-CERT.
Network Vision is a Newburyport, Massachusetts-based company that provides industrial Ethernet solutions for sectors such as automation, critical manufacturing, transportation, and water systems.
IntraVUE, the company’s flagship product, is designed to provide Ethernet device visualization and enable organizations to quickly identify issues affecting devices deployed in distributed and hostile environments. The solution can be used to identify duplicate MAC and IP addresses, connection or application faults, device or cable moves, and unauthorized connections.
