The vulnerability stems from the inclusion of static user credentials for the root account, a practice typically reserved for development purposes. This security concern has been assigned the tracking number CVE-2023-20101 and has received a CVSS score of 9.8.

Cisco has issued the following warning regarding the exploitation potential of this vulnerability: “An attacker could exploit this vulnerability by using the account to log in to an affected system,” Cisco warns.

“This vulnerability could potentially be exploited.” “A successful exploit could allow the attacker to log in to the affected system and execute arbitrary commands as the root user.”

Cisco Issues Urgent Patch to Address Critical Flaw in Emergency Responder Systems

The affected software version, Cisco Emergency Responder Release 12.5(1)SU4, has been successfully addressed in the latest version, 12.5(1)SU5. It’s important to note that this vulnerability does not impact other versions of the product in any manner.

The preeminent networking equipment manufacturer discovered this vulnerability during routine internal security testing. As of now, there’s no knowledge of any malicious exploitation of the vulnerability in the wild.

Less than a week has passed since Cisco’s notification of attempted exploitation of a security issue in its IOS Software and IOS XE Software (CVE-2023-20109, CVSS score: 6.6). This vulnerability could enable an authenticated remote attacker to execute remote code on vulnerable systems. This disclosure arises as a direct consequence of this discovery.

In light of this situation, customers are strongly advised to upgrade to the latest version to safeguard themselves against potential threats, as no interim fixes are currently available.
