VAR-201205-0144
Vulnerability from variot - Updated: 2025-04-11 22:49Integer overflow in the server in xArrow before 3.4.1 allows remote attackers to execute arbitrary code via a crafted packet that triggers an out-of-bounds read operation. xArrow is a lightweight but full-featured industrial configuration software for monitoring and controlling industrial systems. xArrow has multiple security vulnerabilities that allow an attacker to perform a denial of service attack. An attacker can send a malicious message, trigger an uncompressed NULL pointer, heap corruption, illegal read access, memory corruption, etc., which can cause the application to crash. xArrow is prone to multiple remote denial-of-service vulnerabilities. Successful exploits of these vulnerabilities will result in a denial-of-service condition. Due to nature of these issues, arbitrary code execution may also be possible. xArrow 3.2 and prior versions are vulnerable

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
