CVE-2025-43713: ASNA Assist and ASNA Registrar before 2025-03-31 allow deserialization attacks against .NET remoting.
Noroxi assessment
Priority: Monitor (action score 26/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.45% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.

ASNA Assist and ASNA Registrar before 2025-03-31 allow deserialization attacks against .NET remoting. These are Windows system services that support license key management and deprecated Windows network authentication. The services are implemented with .NET remoting and can be exploited via well-known deserialization techniques inherent in the technology. Because the services run with SYSTEM-level rights, exploits can be crafted to achieve escalation of privilege and arbitrary code execution. This affects DataGate for SQL Server 17.0.36.0 and 16.0.89.0, DataGate Component Suite 17.0.36.0 and 16.0.89.0, DataGate Monitor 17.0.26.0 and 16.0.65.0, DataGate WebPak 17.0.37.0 and 16.0.90.0, Monarch for .NET 11.4.50.0 and 10.0.62.0, Encore RPG 4.1.36.0, Visual RPG .NET FW 17.0.37.0 and 16.0.90.0, Visual RPG .NET FW Windows Deployment 17.0.36.0 and 16.0.89.0, WingsRPG 11.0.38.0 and 10.0.95.0, Mobile RPG 11.0.35.0 and 10.0.94.0, Monarch Framework for .NET FW 11.0.36.0 and 10.0.89.0, Browser Terminal 17.0.37.0 and 16.0.90.0, Visual RPG Classic 5.2.7.0 and 5.1.17.0, Visual RPG Deployment 5.2.7.0 and 5.1.17.0, and DataGate Studio 17.0.38.0 and 16.0.104.0.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
No history yet (it accumulates with the daily EPSS job).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Weakness class (CWE)
CWE-502 · Deserialization of Untrusted DataCVSS vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
nvd-secondary
Root cause
Data received over the network is deserialized into the language’s native object format without verifying its source. Code paths inside the object can be triggered during deserialization.
