CVE-2023-50224
MEDIUMCVE-2023-50224 is a medium-severity (CVSS 6.5) CWE-290 vulnerability in tp-link archer c5 firmware. EPSS puts its 30-day exploitation probability at 17.4% (97th percentile). O3 Security detects and blocks CVE-2023-50224 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

Actively exploited in the wild
- CISA’s SSVC triage classifies this CVE as under active exploitation.
Exploitation and automatability from CISA’s SSVC triage for CVE-2023-50224.
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2023-50224 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 368,770 CVEs with a current EPSS score, this one falls in the 10–50% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Description
TP-Link TL-WR841N dropbearpwd Improper Authentication Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of TP-Link TL-WR841N routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the httpd service, which listens on TCP port 80 by default. The issue results from improper authentication. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-19899.

Vendor / applianceDetect
Inventory every tp-link archer c5 firmware 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 exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the tp-link archer c5 firmware security patch or hotfix for CVE-2023-50224 on the affected version, following the vendor advisory for your exact build.
Workarounds
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 O3 protects you
O3 detects and blocks CVE-2023-50224 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2023-50224. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-50224 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2023-50224 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
