Design/Logic Flaw

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...

Authentication flaw

In VOS user session identifier authentication token is issued to the browser prior to authentication but is not changed after the user successfully logs into the application. Failing to issue a new session ID following a successful login introduces the possibility for an attacker to set up a trap...

CVE-2018-16494

In VOS and overly permissive "umask" may allow for authorized users of the server to gain unauthorized access through insecure file permissions that can result in an arbitrary read, write, or execution of newly created files and directories. Insecure umask setting was present throughout the Versa...

CVE-2018-16494

CVE-2018-16494 affects Versa Networks Versa OS (VOS). The issue is an overly permissive default file-creation mask (umask) that allows authorized server users to obtain unauthorized access via insecure file permissions. This can lead to arbitrary read, write, or execution of newly created files a...

CVE-2018-16495

Versa Networks Versa Operating System (VOS) is affected by a session fixation issue: an authentication token is issued to the browser before authentication and is not changed after a successful login. The underlying problem: the same session ID persists across login, enabling an attacker to set u...

CVE-2018-16495

In VOS user session identifier authentication token is issued to the browser prior to authentication but is not changed after the user successfully logs into the application.

CVE-2018-16499

The CVE-2018-16499 entry concerns Versa Networks Versa VOS. The connected records indicate the issue stems from the use of unapproved SSH encryption protocols or cipher suites, enabling a network-endpoint attacker to perform a man-in-the-middle attack and potentially view communications between a...

CVE-2018-16499

In VOS compromised, an attacker at network endpoints can possibly view communications between an unsuspecting user and the service using man-in-the-middle attacks. Usage of unapproved SSH encryption protocols or cipher suites also violates the Data Protection TSR Technical Security Requirements...

CVE-2019-25030

CVE-2019-25030 affects Versa Director, Versa Analytics and VOS. Passwords were stored without an adaptive hash or KDF, using Merkle-Damgard-based algorithms (e.g., MD5/SHA-1), enabling rainbow-table based cracking. The connected documents indicate the mitigation is to hash with adaptive algorithm...

CVE-2019-25030

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...

CVE-2018-16499: Inadequate Encryption Strength

In VOS compromised, an attacker at network endpoints can possibly view communications between an unsuspecting user and the service using man-in-the-middle attacks. Usage of unapproved SSH encryption protocols or cipher suites also violates the Data Protection TSR Technical Security Requirements...

CVE-2019-25030: Insufficiently Protected Credentials

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...

CVE-2018-16495: Session Fixation

In VOS user session identifier authentication token is issued to the browser prior to authentication but is not changed after the user successfully logs into the application. Failing to issue a new session ID following a successful login introduces the possibility for an attacker to set up a trap...

Versa Networks: Unapproved SSH Encryption Enabled

In VOS compromised, an attacker at network endpoints can possibly view communications between an unsuspecting user and the service using man-in-the-middle attacks. Usage of unapproved SSH encryption protocols or cipher suites also violates the Data Protection TSR Technical Security Requirements...

Versa Networks: Session Fixation Exposure

In VOS user session identifier authentication token is issued to the browser prior to authentication but is not changed after the user successfully logs into the application. Failing to issue a new session ID following a successful login introduces the possibility for an attacker to set up a trap...

CVE-2017-6779: Uncontrolled Resource Consumption

Multiple Cisco products are affected by a vulnerability in local file management for certain system log files of Cisco collaboration products that could allow an unauthenticated, remote attacker to cause high disk utilization, resulting in a denial of service DoS condition. The vulnerability occu...
