Cisco Prime Infrastructure and Evolved Programmable Network Manager Remote Code Execution Vulnerabilities

Multiple vulnerabilities in the web-based management interface of Cisco Prime Infrastructure (PI) and Cisco Evolved Programmable Network (EPN) Manager could allow an authenticated, remote attacker to execute code with root-level privileges on the underlying operating system.

These vulnerabilities exist because the software improperly validates user-supplied input. An attacker could exploit these vulnerabilities by uploading a malicious file to the administrative web interface. A successful exploit could allow the attacker to execute code with root-level privileges on the underlying operating system.

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

Cisco Prime Infrastructure and Evolved Programmable Network Manager Path Traversal Vulnerability

A vulnerability in the web-based management interface of Cisco Prime Infrastructure and Cisco Evolved Programmable Network (EPN) Manager software could allow an authenticated, remote attacker to download and view files within the application that should be restricted.

This vulnerability is due to improper sanitization of user-supplied input in HTTP request parameters that describe filenames. An attacker could exploit this vulnerability by using directory traversal techniques to submit a path to a desired file location. A successful exploit could allow the attacker to view application files that may contain sensitive information.

There are no workarounds that address this vulnerability.

Cisco Prime Infrastructure and Evolved Programmable Network Manager SQL Injection Vulnerabilities

Multiple vulnerabilities in the web-based management interface of Cisco Prime Infrastructure (PI) and Cisco Evolved Programmable Network (EPN) Manager could allow an authenticated, remote attacker to execute arbitrary SQL queries.

These vulnerabilities exist because the software improperly validates user-supplied input in SQL queries. An attacker could exploit these vulnerabilities by sending a crafted HTTP request that contains malicious SQL statements to the affected application. A successful exploit could allow the attacker to view or modify entries in some database tables, affecting the integrity of the data.

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

Cisco NX-OS CLI Command Software Image Signature Verification Vulnerabilities

Multiple vulnerabilities in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device.

The vulnerabilities exist because software digital signatures are not properly verified during CLI command execution. An attacker could exploit these vulnerabilities to install an unsigned software image on an affected device.

Note: If the device has not been patched for the vulnerability previously disclosed in the Cisco Security Advisory cisco-sa-20190306-nxos-sig-verif, a successful exploit could allow the attacker to boot a malicious software image.

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers MPLS OAM Denial of Service Vulnerability

A vulnerability in the Multiprotocol Label Switching (MPLS) Operations, Administration, and Maintenance (OAM) implementation of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, adjacent attacker to trigger a denial of service (DoS) condition on an affected device.

The vulnerability is due to the incorrect handling of certain MPLS OAM packets. An attacker could exploit this vulnerability by sending malicious MPLS OAM packets to an affected device. A successful exploit could allow the attacker to cause the lspv_server process to crash. The crash could lead to system instability and the inability to process or forward traffic though the device, resulting in a DoS condition that require manual intervention to restore normal operating conditions.

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

Cisco NX-OS Software Remote Package Manager Command Injection Vulnerability

A vulnerability in the Remote Package Manager (RPM) subsystem of Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to leverage a time-of-check, time-of-use (TOCTOU) race condition to corrupt local variables, which could lead to arbitrary command injection.

The vulnerability is due to the lack of a proper locking mechanism on critical variables that need to stay static until used. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a set of RPM-related CLI commands. A successful exploit could allow the attacker to perform arbitrary command injection. The attacker would need administrator credentials for the targeted device.

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

Cisco NX-OS Software SSH Key Information Disclosure Vulnerability

A vulnerability in the SSH CLI key management functionality of Cisco NX-OS Software could allow an authenticated, local attacker to expose a user’s private SSH key to all authenticated users on the targeted device. The attacker must authenticate with valid administrator device credentials.

The vulnerability is due to incomplete error handling if a specific error type occurs during the SSH key export. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the CLI. A successful exploit could allow the attacker to expose a user’s private SSH key. In addition, a similar type of error in the SSH key import could cause the passphrase-protected private SSH key to be imported unintentionally.

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