According to "cnet", Cisco Systems released software security updates Wednesday to address denial-of-service and arbitrary command execution vulnerabilities in several products.
The company released new versions of Cisco IOS XR Software to fix an issue with handling fragmented packets that can be exploited to trigger a denial-of-service condition on various Cisco CRS Route Processor cards. The affected cards and the patched software versions available for them are listed in a Cisco advisory.
The company also released security updates for Cisco Identity Services Engine (ISE), a security policy management platform for wired, wireless, and VPN connections. The updates fix a vulnerability that could be exploited by authenticated remote attackers to execute arbitrary commands on the underlying operating system and a separate vulnerability that could allow attackers to bypass authentication and download the product's configuration or other sensitive information, including administrative credentials.
Cisco also released updates that fix a known Apache Struts vulnerability in several of its products, including ISE. Apache Struts is a popular open-source framework for developing Java-based Web applications.
"The impact of this vulnerability on Cisco products varies depending on the affected product," Cisco said in an advisory. "Successful exploitation on Cisco ISE, Cisco Unified SIP Proxy, and Cisco Business Edition 3000 could result in an arbitrary command executed on the affected system."
No authentication is needed to execute the attack on Cisco ISE and Cisco Unified SIP Proxy, but the flaw's successful exploitation on Cisco Business Edition 3000 requires the attacker to have valid credentials or trick a user with valid credentials into executing a malicious URL, the company said.
"Successful exploitation on the Cisco MXE 3500 Series could allow the attacker to redirect the user to a different and possibly malicious website, however arbitrary command execution is not possible on this product," Cisco said.
