Aruba Patches Vulnerabilities in AirWave Product

HPE-owned network access solutions provider Aruba has patched XML external entity (XXE) and cross-site scripting (XSS) vulnerabilities in its AirWave network management platform.

The vulnerabilities were reported to Aruba by Pichaya Morimoto of SEC Consult and independently by two other researchers. Both weaknesses affect AirWave’s VisualRF component.

The XXE flaw, tracked as CVE-2016-8526, allows a low-privileged user to read files on the system, including ones that could include passwords, which could lead to privilege escalation.

According to Aruba, this security hole is considered low risk on AirWave systems with a single administrator, but the risk increases in environments with users that have different privilege levels.

“The vulnerability can be exploited by a low privileged read-only user to read sensitive information / files with malicious XML code,” SEC Consult said in its advisory. “Note that as Aruba's passwords are encrypted with a shared static key, privilege escalation to admin role is also possible!”

The reflected XSS flaw, identified as CVE-2016-8527, can allow an attacker to obtain sensitive information, such as passwords and session cookies, but they need to trick an AirWave administrator into clicking on a specially crafted link.

The vulnerabilities were reported by SEC Consult in late November 2016 and they were fixed on February 21 with the release of AirWave 8.2.3.1. SEC Consult has classified the flaws as “high impact,” but Aruba has assigned them a “medium” severity rating.

Last year, Google security engineer Sven Blumenstein reported finding more than two dozen vulnerabilities in Aruba products, including ArubaOS, AirWave and Aruba Instant.

This is also not the first time SEC Consult has analyzed Aruba products. As part of its research into the reuse of cryptographic keys, the security firm discovered that Aruba had been using the same certificate for tens of thousands of devices.

Aruba has been running a private bug bounty program on BugCrowd with rewards of up to $1,500 per vulnerability.
