Safety {hardware} producer SonicWall warned clients as we speak of what it describes as a “limitation” of the online content material filtering (WCF) function on Home windows 11, model 22H2 programs.

SonicWall’s Seize Consumer is the corporate’s Home windows and macOS safety resolution with Endpoint Detection & Response (EDR) capabilities that may be managed utilizing the corporate’s Cloud Administration Console service.

The WCF function permits admins to configure insurance policies that enable or block entry to numerous domains/IP addresses, allow internet exercise reporting for simpler monitoring, and throttle bandwidth.

“We have now recognized an inconsistency in Seize Consumer Home windows 3.7.6 and older shoppers on endpoints working Home windows 11 model 22H2,” the corporate stated in an advisory printed on Wednesday.

“This ends in Internet Content material Filtering (WCF) insurance policies that implement blocked classes to be not efficient on impacted endpoints. The flexibility to permit or block domains/URLs utilizing customized lists continues to operate usually.”

Since category-based blocking insurance policies (essential in proscribing entry to malicious, unlawful, or inappropriate internet content material) not work, Home windows 11 22H2 customers at the moment are inclined to potential safety dangers by enabling entry to beforehand restricted domains and URLs.

​The service is damaged as a result of the encrypted and decrypted requests and responses exchanged between Home windows endpoints and SonicWall Content material Filtering Service are despatched utilizing Microsoft’s Cryptographic Utility Programming Interface (CryptoAPI).

Nevertheless, as SonicWall additional explains, “in Home windows 11 model 22H2, Microsoft CryptoAPIs have been modified, making Seize Consumer unable to decrypt responses from the SonicWall Content material Filtering Service.”

The corporate says it is at the moment engaged on a repair for this concern which will likely be made accessible with the discharge of Seize Consumer 3.7.7 for Home windows on February seventeenth. 

As an interim measure, SonicWall has suggested directors to forego updating their Home windows endpoints to the newest Home windows 11 model to keep away from breaking content material filtering.

“As a brief workaround, we suggest endpoints working Home windows 11 not be upgraded to model 22H2 till Seize Consumer 3.7.7 for Home windows is obtainable,” SonicWall stated.
