Title
Cisco Nexus Dashboard Privilege Escalation Vulnerabilities
Summary
Multiple vulnerabilities in Cisco Nexus Dashboard could allow an authenticated, local attacker to elevate privileges on an affected device. These vulnerabilities are due to insufficient input validation during CLI command execution on an affected device. An attacker could exploit these vulnerabilities by authenticating as the rescue-user and executing vulnerable CLI commands using a malicious payload. A successful exploit could allow the attacker to elevate privileges to root on an affected device.

Title
Cisco Nexus Dashboard Privilege Escalation Vulnerabilities
Summary
Multiple vulnerabilities in Cisco Nexus Dashboard could allow an authenticated, local attacker to elevate privileges on an affected device. These vulnerabilities are due to insufficient input validation during CLI command execution on an affected device. An attacker could exploit these vulnerabilities by authenticating as the rescue-user and executing vulnerable CLI commands using a malicious payload. A successful exploit could allow the attacker to elevate privileges to root on an affected device.

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
file.copy operations in GruntJS are vulnerable to a TOCTOU race condition leading to arbitrary file write in gruntjs/grunt
Summary
file.copy operations in GruntJS are vulnerable to a TOCTOU race condition leading to arbitrary file write in GitHub repository gruntjs/grunt prior to 1.5.3. This vulnerability is capable of arbitrary file writes which can lead to local privilege escalation to the GruntJS user if a lower-privileged user has write access to both source and destination directories as the lower-privileged user can create a symlink to the GruntJS user's .bashrc file or replace /etc/shadow file if the GruntJS user is root.

Mitigation
Implementation
The most basic advice for TOCTOU vulnerabilities is to not perform a check before the use. This does not resolve the underlying issue of the execution of a function on a resource whose state and identity cannot be assured, but it does help to limit the false sense of security given by the check.
Mitigation
Implementation
When the file being altered is owned by the current user and group, set the effective gid and uid to that of the current user and group when executing this statement.
Mitigation
Architecture and Design
Limit the interleaving of operations on files from multiple processes.
Mitigation
Implementation
Architecture and Design
If you cannot perform operations atomically and you must share access to the resource between multiple processes or threads, then try to limit the amount of time (CPU cycles) between the check and use of the resource. This will not fix the problem, but it could make it more difficult for an attack to succeed.
Mitigation
Implementation
Recheck the resource after the use call to verify that the action was taken appropriately.
Mitigation
Architecture and Design
Ensure that some environmental locking mechanism can be used to protect resources effectively.
Mitigation
Implementation
Ensure that locking occurs before the check, as opposed to afterwards, such that the resource, as checked, is the same as it is when in use.
CAPEC-27: Leveraging Race Conditions via Symbolic Links
This attack leverages the use of symbolic links (Symlinks) in order to write to sensitive files. An attacker can create a Symlink link to a target file not otherwise accessible to them. When the privileged program tries to create a temporary file with the same name as the Symlink link, it will actually write to the target file pointed to by the attackers' Symlink link. If the attacker can insert malicious content in the temporary file they will be writing to the sensitive file by using the Symlink. The race occurs because the system checks if the temporary file exists, then creates the file. The attacker would typically create the Symlink during the interval between the check and the creation of the temporary file.
CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
