Title
Gladinet Triofox Unchecked Return Value to NULL Pointer Dereference DOS
Summary
Function calls to WOSCommonUtil.dll!WOSSysInfoGetDeviceInterface() in various DLLs (i.e., WOSProfileMgrModule.dll, WOSWebDavModule.dll) can return a NULL pointer (i.e., when no user is logged into the Triofox Server Agent Management Console). The returned NULL pointer is not checked before being dereferenced.

Title
Gladinet Triofox WOSHttpStatusModule.dll NULL Function Pointer Call DoS
Summary
When processing a request with a URL path starting with /status or /sysinfo, WOSHttpStatusModule.dll is to be loaded to handle such URL patterns. The WOSBin_LoadHttpModule function in the dll would be called to set up a "module" object for that module. However, WOSHttpStatusModule.dll is not present in the installation. As a result, a function pointer to WOSBin_LoadHttpModule (which would have been in the export table in WOSHttpStatusModule.dll) is set to NULL, resulting in calling a function at address 0.

Title
Post-auth null pointer dereference when aggregating against a view with empty search pipeline
Summary
An authenticated user can crash mongod when running $rankFusion or $scoreFusion with an empty pipeline on a view.
When resolving a view, the server inspects the aggregation pipeline to determine whether it begins with an Atlas Search stage. For $rankFusion and $scoreFusion, this inspection reads the first element on each stage’s input pipeline array without first verifying that the array is non-empty. Supplying an empty pipeline causes a null pointer dereference and crashes the server.
This issue affects MongoDB Server 8.2 versions prior to 8.2.7.

Title
Telegram Desktop Bot API url_auth_box.cpp RequestButton null pointer dereference
Summary
A security vulnerability has been detected in Telegram Desktop up to 6.7.5. This vulnerability affects the function RequestButton of the file Telegram/SourceFiles/boxes/url_auth_box.cpp of the component Bot API. The manipulation of the argument login_url leads to null pointer dereference. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. There is ongoing doubt regarding the real existence of this vulnerability. Upgrading to version 6.7.6 is able to resolve this issue. Upgrading the affected component is recommended. The vendor provides this rationale for the dispute: "[T]he described scenario does not lead to any security issue or vulnerability, and only causes a one-time crash. In the outlined scenario, the targeted user must perform an active action, which doesn't produce any consequences after the app is relaunched."

Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Requirements
Select a programming language that is not susceptible to these issues.
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
No CAPEC attack patterns related to this CWE.
