PRODUCT DESCRIPTION

RUGGEDCOM CROSSBOW is a secure access management solution designed to provide NERC CIP compliant access to Intelligent Electronic Devices.

VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability CVE-2025-3277

An integer overflow can be triggered in SQLite's 'concat_ws()' function. The resulting, truncated integer is then used to allocate a buffer. When SQLite then writes the resulting string to the buffer, it uses the original, untruncated size and thus a wild Heap Buffer overflow of size 4GB can be triggered. This can result in arbitrary code execution.

CVSS v3.1 Base Score	8.3
CVSS v3.1 Vector	CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L
CVSS v4.0 Base Score	6.9
CVSS v4.0 Vector	CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L
CWE	CWE-122: Heap-based Buffer Overflow

Vulnerability CVE-2025-29087

In SQLite, the concat_ws() SQL function can cause memory to be written beyond the end of a malloc-allocated buffer. If the separator argument is attacker-controlled and has a large string (e.g., 2MB or more), an integer overflow occurs in calculating the size of the result buffer, and thus malloc may not allocate enough memory.

CVSS v3.1 Base Score	5.5
CVSS v3.1 Vector	CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C
CWE	CWE-190: Integer Overflow or Wraparound

Vulnerability CVE-2025-29088

A vulnerability in sqlite allows an attacker to cause a denial of service via the SQLITE_DBCONFIG_LOOKASIDE component.

CVSS v3.1 Base Score	7.5
CVSS v3.1 Vector	CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C
