CVE-2025-9189: CWE-1285 Improper Validation of Specified Index, Position, or Offset in Input in Digilent DASYLab
There is an out of bounds write vulnerability due to improper bounds checking resulting in a large destination address when parsing a DSB file with Digilent DASYLab. This vulnerability may result in arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted DSB file. The vulnerability affects all versions of DASYLab.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-9189) in Digilent DASYLab arises from improper validation of specified index, position, or offset in input (CWE-1285). Specifically, when parsing a DSB file, insufficient bounds checking allows an out-of-bounds write to a large destination address. Successful exploitation requires a user to open a maliciously crafted DSB file, potentially resulting in arbitrary code execution. The vulnerability affects all versions of DASYLab. No patch or remediation information is currently provided.
Potential Impact
An attacker who convinces a user to open a specially crafted DSB file can exploit this vulnerability to execute arbitrary code with the privileges of the user. This can lead to full compromise of the affected system. The vulnerability is rated high severity with a CVSS score of 7.8, reflecting high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should avoid opening untrusted DSB files and apply standard caution with files from unknown sources.
