| Duende.AccessTokenManagement is a set of .NET libraries that manage OAuth and OpenId Connect access tokens. Duende.AccessTokenManagement contains a race condition when requesting access tokens using the client credentials flow. Concurrent requests to obtain an access token using differing protocol parameters can return access tokens obtained with the wrong scope, resource indicator, or other protocol parameters. Such usage is somewhat atypical, and only a small percentage of users are likely to be affected. Duende.AccessTokenManagement can request access tokens using the client credentials flow in several ways. In basic usage, the client credentials flow is configured once and the parameters do not vary. In more advanced situations, requests with varying protocol parameters may be made by calling specific overloads of these methods: `HttpContext.GetClientAccessTokenAsync()` and `IClientCredentialsTokenManagementService.GetAccessTokenAsync()`. There are overloads of both of these methods that accept a `TokenRequestParameters` object that customizes token request parameters. However, concurrent requests with varying `TokenRequestParameters` will result in the same token for all concurrent calls. Most users can simply update the NuGet package to the latest version. Customizations of the `IClientCredentialsTokenCache` that derive from the default implementation (`DistributedClientCredentialsTokenCache`) will require a small code change, as its constructor was changed to add a dependency on the `ITokenRequestSynchronization` service. The synchronization service will need to be injected into the derived class and passed to the base constructor. The impact of this vulnerability depends on how Duende.AccessTokenManagement is used and on the security architecture of the solution. Most users will not be vulnerable to this issue. More advanced users may run into this issue by calling the methods specified above with customized token request parameters. The impact of obtaining an access token with different than intended protocol parameters will vary depending on application logic, security architecture, and the authorization policy of the resource servers. |
| Velocidex WinPmem versions 4.1 and below suffer from an Improper Input Validation vulnerability whereby an attacker with admin access can trigger a BSOD with a parallel thread changing the memory’s access right under the control of the user-mode application. This is due to verification only being performed at the beginning of the routine allowing the userspace to change page permissions half way through the routine. A valid workaround is a rule to detect unauthorized loading of winpmem outside incident response operations. |
| Time-of-check Time-of-use Race Condition in some Intel(R) processors with Intel(R) ACTM may allow a privileged user to potentially enable escalation of privilege via local access. |
| There exists a TOCTOU race condition in TvSettings AppRestrictionsFragment.java that lead to start of attacker supplied activity in Settings’ context, i.e. system-uid context, thus lead to launchAnyWhere. The core idea is to utilize the time window between the check of Intent and the use to Intent to change the target component’s state, thus bypass the original security sanitize function. |
| A race condition exists in the Falcon sensor for Windows that could allow an attacker, with the prior ability to execute code on a host, to delete arbitrary files. CrowdStrike released a security fix for this issue in Falcon sensor for Windows versions 7.24 and above and all Long Term Visibility (LTV) sensors.
There is no indication of exploitation of these issues in the wild. Our threat hunting and intelligence team are actively monitoring for exploitation and we maintain visibility into any such attempts.
The Falcon sensor for Mac, the Falcon sensor for Linux and the Falcon sensor for Legacy Systems are not impacted by this.
CrowdStrike was made aware of this issue through our HackerOne bug bounty program. It was discovered by Cong Cheng and responsibly disclosed. |
| Open OnDemand is an open-source HPC portal. Prior to versions 4.0.8 and 3.1.16, users can craft a "Time of Check to Time of Use" (TOCTOU) attack when downloading zip files to access files outside of the OOD_ALLOWLIST. This vulnerability impacts sites that use the file browser allowlists in all current versions of OOD. However, files accessed are still protected by the UNIX permissions. Open OnDemand versions 4.0.8 and 3.1.16 have been patched for this vulnerability. |
| OpenSSH 9.5 through 9.7 before 9.8 sometimes allows timing attacks against echo-off password entry (e.g., for su and Sudo) because of an ObscureKeystrokeTiming logic error. Similarly, other timing attacks against keystroke entry could occur. |
| In deletefiles in FDUPES before 2.2.0, a TOCTOU race condition allows arbitrary file deletion via a symlink. |
| Race condition in the Zoom Workplace VDI Plugin macOS Universal installer for VMware Horizon before version 6.4.10 (or before 6.2.15 and 6.3.12 in their respective tracks) may allow an authenticated user to conduct a disclosure of information via network access. |
| Rack::Session is a session management implementation for Rack. In versions starting from 2.0.0 to before 2.1.1, when using the Rack::Session::Pool middleware, and provided the attacker can acquire a session cookie (already a major issue), the session may be restored if the attacker can trigger a long running request (within that same session) adjacent to the user logging out, in order to retain illicit access even after a user has attempted to logout. This issue has been patched in version 2.1.1. |
| Screen version 5.0.0 and older version 4 releases have a TOCTOU race potentially allowing to send SIGHUP, SIGCONT to privileged processes when installed setuid-root. |
| A Time-of-check time-of-use (TOCTOU) race condition in the SMM communications buffer could allow a privileged attacker to bypass input validation and perform an out of bounds read or write, potentially resulting in loss of confidentiality, integrity, or availability. |
| Time-of-check Time-of-use race condition in Intel(R) Neural Compressor software before version 2.5.0 may allow an authenticated user to potentially enable information disclosure via local access. |
| An issue was discovered in Alcatel-Lucent ALE NOE deskphones through 86x8_NOE-R300.1.40.12.4180 and SIP deskphones through 86x8_SIP-R200.1.01.10.728. Because of a time-of-check time-of-use vulnerability, an authenticated attacker is able to replace the verified firmware image with malicious firmware during the update process. |
| Link Following Local Privilege Escalation Vulnerability in NortonUtilitiesSvc in Norton Utilities Ultimate Version 24.2.16862.6344 on Windows 10 Pro x64 allows local attackers to escalate privileges and execute arbitrary code in the context of SYSTEM via the creation of a symbolic link and leveraging a TOCTTOU (time-of-check to time-of-use) attack. |
| A race condition vulnerability exists in Armoury Crate. This vulnerability arises from a Time-of-check Time-of-use issue, potentially leading to authentication bypass.
Refer to the 'Security Update for Armoury Crate App' section on the ASUS Security Advisory for more information. |
| Race condition in BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access. |
| A Time-of-Check to Time-of-Use (TOCTOU) vulnerability has been identified in the driver of the NDD Print solution, which could allow an unprivileged user to exploit this flaw and gain SYSTEM-level access on the device. The vulnerability affects version 5.24.3 and before of the software. |
| A path traversal vulnerability has been reported to affect several product versions. If a local attacker gains a user account, they can then exploit the vulnerability to read the contents of unexpected files or system data.
We have already fixed the vulnerability in the following versions:
Qfinder Pro Mac 7.13.0 and later
Qsync for Mac 5.1.5 and later
QVPN Device Client for Mac 2.2.8 and later |
| Link Following Local Privilege Escalation Vulnerability in TuneupSvc in Avast Cleanup Premium Version 24.2.16593.17810 on Windows 10 Pro x64 allows local attackers to escalate privileges and execute arbitrary code in the context of SYSTEM via creating a symbolic link and leveraging a TOCTTOU (time-of-check to time-of-use) attack. |
