Summary
Race condition for some TDX Module before version tdx1.5 within Ring 0: Hypervisor may allow a denial of service. Authorized adversary with a privileged user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts.

Title
Next.js Race Condition to Cache Poisoning
Summary
Next.js is a React framework for building full-stack web applications. Versions prior to 14.2.24 and 15.1.6 have a race-condition vulnerability. This issue only affects the Pages Router under certain misconfigurations, causing normal endpoints to serve `pageProps` data instead of standard HTML. This issue was patched in versions 15.1.6 and 14.2.24 by stripping the `x-now-route-matches` header from incoming requests. Applications hosted on Vercel's platform are not affected by this issue, as the platform does not cache responses based solely on `200 OK` status without explicit `cache-control` headers. Those who self-host Next.js deployments and are unable to upgrade immediately can mitigate this vulnerability by stripping the `x-now-route-matches` header from all incoming requests at the content development network and setting `cache-control: no-store` for all responses under risk. The maintainers of Next.js strongly recommend only caching responses with explicit cache-control headers.

Title
Rack session gets restored after deletion
Summary
Rack is a modular Ruby web server interface. Prior to version 2.2.14, when using the `Rack::Session::Pool` middleware, simultaneous rack requests can restore a deleted rack session, which allows the unauthenticated user to occupy that session. Rack session middleware prepares the session at the beginning of request, then saves is back to the store with possible changes applied by host rack application. This way the session becomes to be a subject of race conditions in general sense over concurrent rack requests. 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. Version 2.2.14 contains a patch for the issue. Some other mitigations are available. Either ensure the application invalidates sessions atomically by marking them as logged out e.g., using a `logged_out` flag, instead of deleting them, and check this flag on every request to prevent reuse; or implement a custom session store that tracks session invalidation timestamps and refuses to accept session data if the session was invalidated after the request began.

A vulnerability has been identified in RUGGEDCOM RST2428P (6GK6242-6PA00) (All versions < V3.2), SCALANCE XCH328 (6GK5328-4TS01-2EC2) (All versions < V3.2), SCALANCE XCM324 (6GK5324-8TS01-2AC2) (All versions < V3.2), SCALANCE XCM328 (6GK5328-4TS01-2AC2) (All versions < V3.2), SCALANCE XCM332 (6GK5332-0GA01-2AC2) (All versions < V3.2), SCALANCE XRH334 (24 V DC, 8xFO, CC) (6GK5334-2TS01-2ER3) (All versions < V3.2), SCALANCE XRM334 (230 V AC, 12xFO) (6GK5334-3TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (230 V AC, 8xFO) (6GK5334-2TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (230V AC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (24 V DC, 12xFO) (6GK5334-3TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (24 V DC, 8xFO) (6GK5334-2TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (24V DC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (2x230 V AC, 12xFO) (6GK5334-3TS01-4AR3) (All versions < V3.2), SCALANCE XRM334 (2x230 V AC, 8xFO) (6GK5334-2TS01-4AR3) (All versions < V3.2), SCALANCE XRM334 (2x230V AC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-4AR3) (All versions < V3.2). The "Load Configuration from Local PC" functionality in the web interface of affected products contains a race condition vulnerability. This could allow an authenticated remote attacker to make the affected product load an attacker controlled configuration instead of the legitimate one. Successful exploitation requires that a legitimate administrator invokes the functionality and the attacker wins the race condition.

Title
Rack session gets restored after deletion
Summary
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.

Mitigation

Phase: Architecture and Design

Description:

  • In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.
Mitigation

Phase: Architecture and Design

Description:

  • Use thread-safe capabilities such as the data access abstraction in Spring.
Mitigation

Phase: Architecture and Design

Description:

  • Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.
  • Additionally, this will minimize the amount of synchronization necessary and may even help to reduce the likelihood of a denial of service where an attacker may be able to repeatedly trigger a critical section (CWE-400).
Mitigation

Phase: Implementation

Description:

  • When using multithreading and operating on shared variables, only use thread-safe functions.
Mitigation

Phase: Implementation

Description:

  • Use atomic operations on shared variables. Be wary of innocent-looking constructs such as "x++". This may appear atomic at the code layer, but it is actually non-atomic at the instruction layer, since it involves a read, followed by a computation, followed by a write.
Mitigation

Phase: Implementation

Description:

  • Use a mutex if available, but be sure to avoid related weaknesses such as CWE-412.
Mitigation

Phase: Implementation

Description:

  • Avoid double-checked locking (CWE-609) and other implementation errors that arise when trying to avoid the overhead of synchronization.
Mitigation

Phase: Implementation

Description:

  • Disable interrupts or signals over critical parts of the code, but also make sure that the code does not go into a large or infinite loop.
Mitigation

Phase: Implementation

Description:

  • Use the volatile type modifier for critical variables to avoid unexpected compiler optimization or reordering. This does not necessarily solve the synchronization problem, but it can help.
Mitigation ID: MIT-17

Phases: Architecture and Design, Operation

Strategy: Environment Hardening

Description:

  • Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
CAPEC-26: Leveraging Race Conditions

The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious 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.
