Container Privilege Escalation Vulnerability Affecting Cisco Products: February 2019

Cisco Leave a comment

A vulnerability in the Open Container Initiative runc CLI tool used by multiple products could allow an unauthenticated, remote attacker to escalate privileges on a targeted system.

The vulnerability exists because the affected software improperly handles file descriptors related to /proc/self/exe. An attacker could exploit the vulnerability either by persuading a user to create a new container using an attacker-controlled image or by using the docker exec command to attach into an existing container that the attacker already has write access to. A successful exploit could allow the attacker to overwrite the host’s runc binary file with a malicious file, escape the container, and execute arbitrary commands with root privileges on the host system.

This advisory will be updated as additional information becomes available.

Scan result showed risk “Heur.AdvML.B”, but said the file was not infected, but deleted some files, but did not specify what files were deleted

Symantec Community Leave a comment
I need a solution

Attached screenshot is the scan result in excel, with system/file info removed.

The result is so confusing.

Some files had risk but were not infected, so they were left alone?

Some files were Cleaned by Deletion, but he file name were “SUMMARIZED DATA”?

Can some explain the result to me? Was/is there really virus in my computer? Was any file really deleted?

Cisco Elastic Services Controller Service Portal Unauthorized Access Vulnerability

Cisco Leave a comment
A vulnerability in the use of JSON web tokens by the web-based service portal of Cisco Elastic Services Controller Software could allow an unauthenticated, remote attacker to gain administrative access to an affected system.

The vulnerability is due to the presence of static default credentials for the web-based service portal of the affected software. An attacker could exploit this vulnerability by extracting the credentials from an image of the affected software and using those credentials to generate a valid administrative session token for the web-based service portal of any other installation of the affected software. A successful exploit could allow the attacker to gain administrative access to the web-based service portal of an affected system.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco TelePresence Management Suite Simple Object Access Protocol Vulnerability

Cisco Leave a comment

A vulnerability in the Simple Object Access Protocol (SOAP) of Cisco TelePresence Management Suite (TMS) software could allow an unauthenticated, remote attacker to gain unauthorized access to an affected device.

The vulnerability is due to a lack of proper access and authentication controls on the affected TMS software. An attacker could exploit this vulnerability by gaining access to internal, trusted networks to send crafted SOAP calls to the affected device. If successful, an exploit could allow the attacker to access system management tools. Under normal circumstances, this access should be prohibited.

There are no workarounds that address this vulnerability.

Multiple Cisco Unified Communications Products Reflected Cross-Site Scripting Vulnerability

Cisco Leave a comment
A vulnerability in the web-based management interface of Cisco Emergency Responder and Cisco Unified Communications Manager could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.

The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the web-based management interface to click a link that submits malicious input to the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information.

There are no workarounds that address this vulnerability.

Cisco Small Business RV320 and RV325 Routers Command Injection Vulnerability

Cisco Leave a comment

A vulnerability in the web-based management interface of Cisco Small Business RV320 and RV325 Dual Gigabit WAN VPN Routers could allow an authenticated, remote attacker with administrative privileges on an affected device to execute arbitrary commands.

The vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending malicious HTTP POST requests to the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux shell as root.

Cisco has released firmware updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Identity Services Engine Privilege Escalation Vulnerability

Cisco Leave a comment

A vulnerability in the administrative web interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to gain additional privileges on an affected device.

The vulnerability is due to improper controls on certain pages in the web interface. An attacker could exploit this vulnerability by authenticating to the device with an administrator account and sending a crafted HTTP request. A successful exploit could allow the attacker to create additional Admin accounts with different user roles. An attacker could then use these accounts to perform actions within their scope. The attacker would need valid Admin credentials for the device. This vulnerability cannot be exploited to add a Super Admin account.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco SD-WAN Solution Unauthorized Access Vulnerability

Cisco Leave a comment

A vulnerability in the Cisco SD-WAN Solution could allow an authenticated, adjacent attacker to bypass authentication and have direct unauthorized access to other vSmart containers.

The vulnerability is due to an insecure default configuration of the affected system. An attacker could exploit this vulnerability by directly connecting to the exposed services. An exploit could allow the attacker to retrieve and modify critical system files.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco SD-WAN Solution Buffer Overflow Vulnerability

Cisco Leave a comment

A vulnerability in the vContainer of the Cisco SD-WAN Solution could allow an authenticated, remote attacker to cause a denial of service (DoS) condition and execute arbitrary code as the root user.

The vulnerability is due to improper bounds checking by the vContainer. An attacker could exploit this vulnerability by sending a malicious file to an affected vContainer instance. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected vContainer, which could result in a DoS condition that the attacker could use to execute arbitrary code as the root user.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
