Title
Ashlar-Vellum Graphite VC6 File Parsing Uninitialized Variable Remote Code Execution Vulnerability
Summary
Ashlar-Vellum Graphite VC6 File Parsing Uninitialized Variable Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Graphite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of VC6 files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25475.

Title
WOLFBOX Level 2 EV Charger BLE Encryption Keys Uninitialized Variable Authentication Bypass Vulnerability
Summary
WOLFBOX Level 2 EV Charger BLE Encryption Keys Uninitialized Variable Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of WOLFBOX Level 2 EV Charger devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of cryptographic keys used in vendor-specific encrypted communications. The issue results from the lack of proper initialization of a variable prior to accessing it. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-26295.

Title
Dereferencing of an uninitialized pointer leads to denial of service.
Summary
The Honeywell Experion PKS contains an Uninitialized Variable in the common Epic Platform Analyzer (EPA) communications. An attacker could potentially exploit this vulnerability, leading to a Communication Channel Manipulation, which results in a dereferencing of an uninitialized pointer leading to a denial of service.
Honeywell recommends updating to the most recent version of
Honeywell Experion PKS: 520.2 TCU9 HF1and 530.1 TCU3 HF1. The affected Experion PKS products are
C300 PCNT02, EHB, EHPM, ELMM, Classic ENIM, ETN, FIM4, FIM8, PGM, and RFIM. The Experion PKS versions affected are from 520.1 through 520.2 TCU9 and from 530 through 530 TCU3.
Severity
7.5 (High)

Title
Trimble SketchUp SKP File Parsing Uninitialized Variable Remote Code Execution Vulnerability
Summary
Trimble SketchUp SKP File Parsing Uninitialized Variable Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Trimble SketchUp. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of SKP files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25210.
Severity
7.8 (High)

Mitigation MIT-57
Implementation
Strategy: Attack Surface Reduction
Ensure that critical variables are initialized before first use [REF-1485].
Mitigation
Build and Compilation
Strategy: Compilation or Build Hardening
Most compilers will complain about the use of uninitialized variables if warnings are turned on.
Mitigation
Implementation
Operation
When using a language that does not require explicit declaration of variables, run or compile the software in a mode that reports undeclared or unknown variables. This may indicate the presence of a typographic error in the variable's name.
Mitigation
Requirements
Strategy: Language Selection
Choose a language that is not susceptible to these issues.
Mitigation
Architecture and Design
Mitigating technologies such as safe string libraries and container abstractions could be introduced.
