AP6 Series Wireless Access Points: Unverified Password Change

Published Updated By the CyberSecBulletin desk

CVE-2025-10159 is a critical-severity unverified password change vulnerability in AP6 Series Wireless Access Points from Sophos, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.7.2563 (MR7) as the first without the flaw, so updating AP6 Series Wireless Access Points to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.91% chance of exploitation within 30 days, higher than 60% of scored CVEs.

The underlying weakness: Unverified Password Change

When setting a new password for a user, the product does not require knowledge of the original password, or using another form of authentication.

How developers prevent this class of flaw

  • When prompting for a password change, force the user to provide the original password in addition to the new password.
  • Do not use forgotten password functionality. But if you must, ensure that you are only providing information to the actual user, e.g. by using an email address or challenge question that the legitimate user already provided in the past; do not allow the current user to change this identity information until the correct password has been provided.
