HB810(US2) V1.0/1.6/2.0/2.6: Improper Neutralization of Special Elements used in an OS Command
CVE-2025-30241 is a high-severity improper neutralization of special elements used in an OS command vulnerability in HB810(US2) V1.0/1.6/2.0/2.6 from TP-Link, with a CVSS 4.0 base score of 8.6 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, without any action from a user. The record lists version 0.9.0 3.2.2 v6095.0 Build 260717 Rel.67188n as the first without the flaw, so updating HB810(US2) V1.0/1.6/2.0/2.6 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.41% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update HB810(US2) V1.0/1.6/2.0/2.6 to 0.9.0 3.2.2 v6095.0 Build 260717 Rel.67188n or a later version.
- Update HB810(EU1) V2.0 to 0.10.0 3.2.2 v6095.0 Build 260306 Rel.47567n or a later version.
- Update HB710(US2) V1.6/1.0 to 0.3.0 3.0.0 v60be.0 Build 251128 Rel.43956n or a later version.

Official description
Certain web interface components in affected TP-Link Aginet devices do not validate and sanitize user-supplied input properly before passing it to system-level command execution functions. An authenticated adjacent attacker may inject specially crafted input to execute arbitrary operation system commands with elevated privileges. Successful exploitation may allow execution of arbitrary system commands, potentially leading to full device compromise.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
