Attack-Flow Graph

Executive Summary

This vulnerability is a file parser crash in Catapult DCT2000 versions 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18. It allows a denial of service attack by causing the system to crash when processing specific files.

Detection Guidance

This vulnerability is a file parser crash in Catapult DCT2000 versions 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 that causes denial of service. Detection would require monitoring for crashes or hangs in the DCT2000 application when processing specific files. Check logs for segmentation faults or application failures during file parsing operations.

Impact Analysis

The vulnerability can cause system crashes, leading to service disruption and potential loss of access to critical functions. It requires user interaction to trigger, such as opening a maliciously crafted file.

Compliance Impact

This vulnerability causes a denial of service via file parser crash but does not directly impact data confidentiality or integrity. Compliance impact depends on system role and data handling rather than the vulnerability itself.

Mitigation Strategies

Update Catapult DCT2000 to versions outside the vulnerable ranges (4.6.0 to 4.6.7 and 4.4.0 to 4.4.18) to prevent the file parser crash leading to denial of service.
