Summary
A flaw was found in SQLite’s `concat_ws()` function, where an integer overflow can be triggered. The resulting truncated integer can allocate a buffer. When SQLite writes the resulting string to the buffer, it uses the original, untruncated size, and a wild heap buffer overflow size of around 4GB can occur. This issue can result in arbitrary code execution.

1 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • B&R Industrial Automation GmbH Automation Studio <6.5
Summary
An integer overflow vulnerability exists in SQLite's concat_ws() function that can lead to a massive heap buffer overflow. When triggered, the integer overflow results in a truncated size value being used for buffer allocation, while the original untruncated size is used for writing the resulting string, causing a heap buffer overflow of approximately 4GB.
Remediation
The problem is corrected in the following product versions: B&R Automation Studio 6.5 B&R recommends that customers apply the update at earliest convenience. The process to install updates is described in the user manual. The step to identify the installed product version is described in the user manual.

The vendor explicitly identifies these products as affected by this CVE.

  • ABB Ability Camera Connect <=2.0.0.42
Summary
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.
Remediation
The problem is corrected in the following product versions: - ABB Ability Camera Connect 2.0.0.49. The easiest path to mitigate the problem is an update of ABB Ability Camera Connect system by the customer. ABB recommends that customers apply the update at earliest convenience.

What, why and how

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.

What

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.

Why

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
