Title
Local privilege escalation
Summary
Netskope was made aware of a security vulnerability in its NSClient product for version 100 & prior where a malicious non-admin user can disable the Netskope client by using a specially-crafted package. The root cause of the problem was a user control code when called by a Windows ServiceController did not validate the permissions associated with the user before executing the user control code. This user control code had permissions to terminate the NSClient service.

Vulnerability from nvd – Published: 2023-06-15 06:44 – Updated: 2024-12-12 17:05

Title
Local privilege escalation using log file
Summary
The Netskope client service (prior to R96) on Windows runs as NT AUTHORITY\SYSTEM which writes log files to a writable directory (C:\Users\Public\netSkope) for a standard user. The files are created and written with a SYSTEM account except one file (logplaceholder) which inherits permission giving all users full access control list. Netskope client restricts access to this file by allowing only read permissions as a standard user. Whenever the Netskope client service restarts, it deletes the logplaceholder and recreates, creating a race condition, which can be exploited by a malicious local user to create the file and set ACL permissions on the file. Once the file is created by a malicious user with proper ACL permissions, all files within C:\Users\Public\netSkope\ becomes modifiable by the unprivileged user. By using Windows pseudo-symlink, these files can be pointed to other places in the system and thus malicious users will be able to elevate privileges.

CVE-2023-2270 (GCVE-0-2023-2270)
Vulnerability from nvd – Published: 2023-06-15 04:29 – Updated: 2024-08-28 20:30

Title
Local privilege escalation
Summary
The Netskope client service running with NT\SYSTEM privileges accepts network connections from localhost to start various services and execute commands. The connection handling function of Netskope client before R100 in this service utilized a relative path to download and unzip configuration files on the machine. This relative path provided a way for local users to write arbitrary files at a location which is accessible to only higher privileged users. This can be exploited by local users to execute code with NT\SYSTEM privileges on the end machine.
Severity ?

Summary
Netskope client prior to 89.x on macOS is impacted by a local privilege escalation vulnerability. The XPC implementation of nsAuxiliarySvc process does not perform validation on new connections before accepting the connection. Thus any low privileged user can connect and call external methods defined in XPC service as root, elevating their privilege to the highest level.

Title
Client Enrollment Process Bypass
Summary
Netskope was notified about a security gap in Netskope Client enrollment process where NSClient is using a static token “Orgkey” as authentication parameter. Since this is a static token, if leaked, cannot be rotated or revoked. A malicious actor can use this token to enroll NSClient from a customer’s tenant and impersonate a user.

Title
Local privilege escalation
Summary
Netskope was made aware of a security vulnerability in its NSClient product for version 100 & prior where a malicious non-admin user can disable the Netskope client by using a specially-crafted package. The root cause of the problem was a user control code when called by a Windows ServiceController did not validate the permissions associated with the user before executing the user control code. This user control code had permissions to terminate the NSClient service.

Title
Local privilege escalation using log file
Summary
The Netskope client service (prior to R96) on Windows runs as NT AUTHORITY\SYSTEM which writes log files to a writable directory (C:\Users\Public\netSkope) for a standard user. The files are created and written with a SYSTEM account except one file (logplaceholder) which inherits permission giving all users full access control list. Netskope client restricts access to this file by allowing only read permissions as a standard user. Whenever the Netskope client service restarts, it deletes the logplaceholder and recreates, creating a race condition, which can be exploited by a malicious local user to create the file and set ACL permissions on the file. Once the file is created by a malicious user with proper ACL permissions, all files within C:\Users\Public\netSkope\ becomes modifiable by the unprivileged user. By using Windows pseudo-symlink, these files can be pointed to other places in the system and thus malicious users will be able to elevate privileges.

Title
Local privilege escalation
Summary
The Netskope client service running with NT\SYSTEM privileges accepts network connections from localhost to start various services and execute commands. The connection handling function of Netskope client before R100 in this service utilized a relative path to download and unzip configuration files on the machine. This relative path provided a way for local users to write arbitrary files at a location which is accessible to only higher privileged users. This can be exploited by local users to execute code with NT\SYSTEM privileges on the end machine.
Severity ?

Summary
Netskope client prior to 89.x on macOS is impacted by a local privilege escalation vulnerability. The XPC implementation of nsAuxiliarySvc process does not perform validation on new connections before accepting the connection. Thus any low privileged user can connect and call external methods defined in XPC service as root, elevating their privilege to the highest level.
Severity ?
