Summary

CVE-2025-62501 is a high-severity Key Exchange without Entity Authentication (CWE-322) vulnerability in Tp-Link Archer Ax53 Firmware. Its CVSS base score is 7.0 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Adversary-in-the-Middle (T1557); ranked at the 38th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-3 (Device Identification and Authentication) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-62501 is an SSH hostkey misconfiguration vulnerability in the tmpserver modules of TP-Link Archer AX53 v1.0 routers. It affects versions through 1.3.1 Build 20241120 and carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), mapped to CWE-322 (Key Exchange without Entity Authentication). The flaw enables attackers to obtain device credentials via a specially crafted man-in-the-middle (MITM) attack.

Remote attackers with no privileges or user interaction required can exploit this over the network by positioning themselves for an MITM attack, which demands high attack complexity. Successful exploitation allows capture of device credentials, potentially leading to unauthorized access if those credentials are reused elsewhere.

Talos Intelligence advisories, including TALOS-2025-2291, detail the issue, while TP-Link provides firmware downloads on regional support pages (e.g., US, MY, and global) for Archer AX53 v1.0 to mitigate the vulnerability through patching. Security practitioners should verify and apply these updates promptly.

Mitigating Controls (NIST 800-53 r5) AI

Requiring device identification and authentication before establishing connections prevents unauthenticated key exchanges with unknown devices.

Requiring unique identification and authentication of users before any privileged action stops key exchange from occurring with unauthenticated parties.

Requiring identification and authentication of non-organizational users blocks key exchange with unauthenticated external actors.

Requiring proper cryptographic key establishment and management directly stops unauthenticated key-exchange implementations.

Issuing or obtaining PKI certificates under an approved policy supplies the entity authentication missing from unauthenticated key exchange.

prevents

Use of cryptography mandates authenticated key-exchange mechanisms, directly addressing the lack of entity authentication.

finds

Security testing can detect missing entity authentication during key exchange.

prevents

Secure authentication directly prevents unauthenticated key exchange by requiring verified identities before keys are established.

prevents

Identity management provides the verified identities required before key exchange occurs.

mitigates

Network security policies can require authenticated channels, indirectly reducing the risk of unauthenticated key exchange.

mitigates

Security of network services includes requirements for authenticated key exchange in service protocols.
