How severe is CVE-2023-47246?

CVE-2023-47246 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which products are affected by CVE-2023-47246?

CVE-2023-47246 affects the following products: sysaid sysaid on-premises.

How do I patch CVE-2023-47246?

No patch has shipped for CVE-2023-47246 yet — track the sysaid sysaid on-premises advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2023-47246 across my infrastructure?

Inventory every sysaid sysaid on-premises deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2023-47246 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2023-47246?

O3 detects and blocks CVE-2023-47246 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2023-47246 actively exploited in the wild?

Yes. There are 7 known exploit references for CVE-2023-47246, including 6 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2023-47246?

CVE-2023-47246 has an EPSS (Exploit Prediction Scoring System) score of 98.9%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2023-47246 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2023-47246 (SysAid Server Path Traversal Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2023-11-13. CISA required all US federal civilian agencies to remediate this vulnerability by 2023-12-04. The required action was: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. This CVE has been used in known ransomware campaigns. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2023-47246?

CVE-2023-47246 is classified as Path Traversal (CWE-22). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2023-47246?

CVE-2023-47246 affects sysaid sysaid on-premises. Check the affected-products list on this page against your deployed version to confirm exposure.

Is there exploit tooling available for CVE-2023-47246?

A Nuclei detection template exists for CVE-2023-47246, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2023-47246 published, and has it been updated?

CVE-2023-47246 was published on November 10, 2023 and was last updated on July 31, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

CVE-2023-47246

CRITICAL

CVE-2023-47246 is a critical-severity (CVSS 9.8) Path Traversal vulnerability in sysaid sysaid on-premises. It is in CISA's Known Exploited Vulnerabilities catalog (added 2023-11-13) and has been used in ransomware campaigns — treat it as actively exploited and patch now. O3 Security detects and blocks CVE-2023-47246 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

In SysAid On-Premise before 23.3.36, a path traversal vulnerability leads to code execution after an attacker writes a file to the Tomcat webroot, as exploited in the wild in November 2023.

Exploitation Status

Actively exploited in the wild

Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2023-11-13 — including use in ransomware campaigns. Federal agencies were required to remediate by 2023-12-04.
CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.
