Versa Director SD-WAN 2FA Code Replay and Brute-Force Vulnerability
CVE-2025-23168 8.8 - High - June 19, 2025

The Versa Director SD-WAN orchestration platform implements Two-Factor Authentication (2FA) using One-Time Passcodes (OTP) delivered via email or SMS. Versa Director accepts untrusted user input when dispatching 2FA codes, allowing an attacker who knows a valid username and password to redirect the OTP delivery (SMS/email) to their own device. OTP/TOTP codes are not invalidated after use, enabling reuse by an attacker who has previously intercepted or obtained a valid code. In addition, the 2FA system does not adequately restrict the number or frequency of login attempts. The OTP values are generated from a relatively small keyspace, making brute-force attacks more feasible. Exploitation Status: Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers. Workarounds or Mitigation: Versa recommends that Director be upgraded to one of the remediated software versions.

Versa Director Default Credential & Open Services Vulnerability
CVE-2025-24288 - June 19, 2025

The Versa Director software exposes a number of services by default and allow attackers an easy foothold due to default credentials and multiple accounts (most with sudo access) that utilize the same default credentials. By default, Versa director exposes ssh and postgres to the internet, alongside a host of other services. Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers. Workarounds or Mitigation: Versa recommends the following security controls: 1) Change default passwords to complex passwords 2) Passwords must be complex with at least 8 characters that comprise of upper case, and lower case alphabets, as well as at at least one digit, and one special character 3) Passwords must be changed at least every 90 days 4) Password change history is checked to ensure that the at least the last 5 passwords must be used when changing password. 5) Review and audit logs for all authentication attempts to check for unauthorized/suspicious login attempts and enforce remediation steps.

Versa Director SD-WAN RCE via Websockify 6080 Exposure
CVE-2025-23173 - June 19, 2025

The Versa Director SD-WAN orchestration platform provides direct web-based access to uCPE virtual machines through the Director GUI. By default, the websockify service is exposed on port 6080 and accessible from the internet. This exposure introduces significant risk, as websockify has known weaknesses that can be exploited, potentially leading to remote code execution. Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers. Workarounds or Mitigation: Restrict access to TCP port 6080 if uCPE console access is not necessary. Versa recommends that Director be upgraded to one of the remediated software versions.

Versa Director SD-WAN RCE via Unauthorized HA Password (CVE-2024-45208)
CVE-2024-45208 - June 19, 2025

The Versa Director SD-WAN orchestration platform which makes use of Cisco NCS application service. Active and Standby Directors communicate over TCP ports 4566 and 4570 to exchange High Availability (HA) information using a shared password. Affected versions of Versa Director bound to these ports on all interfaces. An attacker that can access the Versa Director could access the NCS service on port 4566 and exploit it to perform unauthorized administrative actions and perform remote code execution. Customers are recommended to follow the hardening guide. Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers.

Versa Director GUI Misuse of Change Favicon Allows Malicious PNG Upload
CVE-2024-39717 - August 22, 2024

The Versa Director GUI provides an option to customize the look and feel of the user interface. This option is only available for a user logged with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin. (Tenant level users do not have this privilege). The Change Favicon (Favorite Icon) option can be mis-used to upload a malicious file ending with .png extension to masquerade as image file. This is possible only after a user with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin has successfully authenticated and logged in.

A XSS vulnerability exists in Versa Director Release: 16.1R2 Build: S8
CVE-2021-39285 6.1 - Medium - September 07, 2021

A XSS vulnerability exists in Versa Director Release: 16.1R2 Build: S8. An attacker can use the administration web interface URL to create a XSS based attack.

XSS

In Versa Director
CVE-2019-25030 - May 26, 2021

In Versa Director, Versa Analytics and VOS, Passwords are not hashed using an adaptive cryptographic hash function or key derivation function prior to storage. Popular hashing algorithms based on the Merkle-Damgardconstruction (such as MD5 and SHA-1) alone are insufficient in thwarting password cracking. Attackers can generate and use precomputed hashes for all possible password character combinations (commonly referred to as "rainbow tables") relatively quickly. The use of adaptive hashing algorithms such asscryptorbcryptor Key-Derivation Functions (i.e.PBKDF2) to hash passwords make generation of such rainbow tables computationally infeasible.

Insufficiently Protected Credentials

In Versa Director, the command injection is an attack in which the goal is execution of arbitrary commands on the host operating system
CVE-2019-25029 - May 26, 2021

In Versa Director, the command injection is an attack in which the goal is execution of arbitrary commands on the host operating system via a vulnerable application. Command injection attacks are possible when an application passes unsafe user supplied data (forms, cookies, HTTP headers etc.) to a system shell. In this attack, the attacker-supplied operating system commands are usually executed with the privileges of the vulnerable application. Command injection attacks are possible largely due to insufficient input validation.

Command Injection

In Versa Director, the unencrypted backup files stored on the Versa deployment contain credentials stored within configuration files
CVE-2018-16498 5.5 - Medium - May 26, 2021

In Versa Director, the unencrypted backup files stored on the Versa deployment contain credentials stored within configuration files. These credentials are for various application components such as SNMP, and SSL and Trust keystores.
