The 2.8.x firmware branch transformed the networking capabilities of the , expanding its utility for both Point-to-Point (PTP) backhauls and Point-to-Multipoint (PTMP) client configurations. The 2.8.1 micro-release serves primarily as a security and stability patch deployed to ensure these new features operate safely.
Prior firmware streams, specifically versions 2.8.0.3 and below, contained critical security gaps. Security audits from organizations like WithSecure™ Labs confirmed that these older versions were vulnerable to authenticated Remote Code Execution (RCE) via command injections in the device's API classes (such as Throughput.php , WanStats.php , and PhyStats.php ). , bringing the known Common Vulnerabilities and Exposures (CVE) count down to zero for this release branch. 2.
