cisco: Indian cyber agency warns users of multiple bugs in Cisco products


New Delhi: India’s Computer Emergency Response Team (CERT-In), which falls under the Ministry of IT, issued an advisory on Monday on three serious vulnerabilities in the networking of major Cisco products that could help hackers to access, infiltrate computer systems and steal data.

Vulnerabilities in products such as routers and mail/web manager could allow the attacker to gain unauthorized access, execute arbitrary commands, and cause a denial of service attack on an affected system, a declared CERT-In in its latest advisory.

The “security bypass vulnerability” exists in the external authentication feature of Cisco Secure Email and Web Manager, formerly known as Cisco Security Management Appliance (SMA) and Cisco Email Security Appliance (ESA).

“An attacker could exploit this vulnerability by entering a specific entry on the affected device’s login page,” the cyber agency said.

Another “denial of service vulnerability” exists in the web management interface of Cisco Small Business Routers “due to insufficient user input validation of incoming HTTP packets”.

This could allow a remote, unauthenticated attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition.

“An attacker could exploit this vulnerability by sending a specially crafted request to the web-based management interface. Successful exploitation of this vulnerability could allow the attacker to execute arbitrary commands on an affected device using root-level privileges,” CERT-In informed.

The third, “Information Disclosure Vulnerability”, was also detected in the web management interface of Cisco Secure Email and Web Manager, which could allow the attacker to access sensitive information, including user credentials from the external authentication server.

“To exploit this vulnerability, an attacker would need valid operator-level (or higher) credentials,” CERT-In said, advising users to apply appropriate updates as posted by Cisco.

Last week, the cyber agency issued an advisory on multiple vulnerabilities in Adobe and Citrix products that could help hackers infiltrate computer systems.

The bugs were reported in Adobe products like InDesign (and earlier versions for Windows and macOS), InCopy, Illustrator, Bridge, and Animate (and earlier versions for Windows and macOS).
