CVE-2022-41989
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSewio’s Real-Time Location System (RTLS) Studio version 2.0.0 up to and including version 2.6.2 does not validate the length of RTLS report payloads during communication. This allows an attacker to send an exceedingly long payload, resulting in an out-of-bounds write to cause a denial-of-service condition or code execution.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSewio RTLS Studio fails to validate the length of incoming RTLS report payloads during network communication. Attackers can send crafted packets with excessively long data, triggering an out-of-bounds write condition that leads to denial of service or potentially remote code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed RTLS Studio versionLocate the Sewio RTLS Studio installation directory and check the version information, typically found in the application binary, installer logs, or version file within the program files folderAffected if The installed version falls within >= 2.0.0 and <= 2.6.2
-
Confirm network listener service is activeCheck if the RTLS Studio network service or daemon is running and listening for incoming RTLS data packets on the configured network portsAffected if The network listener service is active and accepting connections
-
Verify RTLS data input is enabledInspect the RTLS Studio configuration to confirm that RTLS report reception from network sources is enabled, rather than operating in offline or file-only modeAffected if Network-based RTLS report ingestion is enabled in the configuration
-
Check network exposure of RTLS portsReview network firewall rules or binding configuration to determine if RTLS Studio ports are exposed to untrusted network segments or the public internetAffected if RTLS network ports are accessible from untrusted network locations
The environment is affected if Sewio RTLS Studio version 2.0.0 through 2.6.2 is installed with network-based RTLS report reception enabled and accessible.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedImplement strict length/bounds checking on all incoming RTLS report payloads before processing; validate payload size against expected maximum lengths and buffer allocations.
Sewio RTLS Studio version 2.6.3 or later (contact Sewio to confirm the exact fixed release)
- Check the current installed version of Sewio RTLS Studio
- Contact Sewio support directly to confirm the availability of version 2.6.3 or later which addresses CVE-2022-41989
- If available, obtain the upgrade package from official Sewio channels
- Backup the current RTLS Studio configuration and database before upgrading
- Follow Sewio's documented upgrade procedure to install the latest version
- After upgrade, verify that RTLS Studio services start successfully
- Test that RTLS report processing functions normally
