Cisco informed customers on Wednesday that it has patched critical and high-severity vulnerabilities in its Data Center Network Manager network management platform.
"The vulnerability exists because different installations share a static encryption key. An attacker could exploit this vulnerability by using the static key to craft a valid session token. A successful exploit could allow the attacker to perform arbitrary actions through the REST API with administrative privileges," Cisco explained.
The networking giant has fixed several high-severity vulnerabilities in DCNM, including weaknesses that can be exploited for arbitrary command injection, path traversal and arbitrary file writing, and bypassing authorization and escalating privileges.
"The vulnerability is due to a failure in the software to perform proper authentication. An attacker could exploit this vulnerability by browsing to one of the hosted URLs in Cisco DCNM. A successful exploit could allow the attacker to interact with and use certain functions within the Cisco DCNM," Cisco explained.
Cisco says none of these vulnerabilities has been exploited for malicious purposes, which is not surprising considering that the more serious ones were all discovered internally.
