Vulnerabilities

WP Crontrol controls the cron events on WordPress websites. WP Crontrol includes a feature that allows administrative users to create events in the WP-Cron system that store and execute PHP code subject to the restrictive security permissions documented here. While there is no known vulnerability in this feature on its own, there exists potential for this feature to be vulnerable to RCE if it were specifically targeted via vulnerability chaining that exploited a separate SQLi (or similar) vulnerability. This is exploitable on a site if one of the below preconditions are met, the site is vulnerable to a writeable SQLi vulnerability in any plugin, theme, or WordPress core, the site's database is compromised at the hosting level, the site is vulnerable to a method of updating arbitrary options in the wp_options table, or the site is vulnerable to a method of triggering an arbitrary action, filter, or function with control of the parameters. As a hardening measure, WP Crontrol version 1.16.2 ships with a new feature that prevents tampering of the code stored in a PHP cron event.

Billion Smart Energy Router SG600R2 Firmware v3.02.rc6 allows an authenticated attacker to gain root execution privileges over the device via a hidden etc_ro/web/adm/system_command.asp shell feature.

The Billion 5200W-T 1.02b.rc5.dt49 router distributed by TrueOnline has a command injection vulnerability in the Remote System Log forwarding function, which is accessible by an unauthenticated user. The vulnerability is in the adv_remotelog.asp page and can be exploited through the syslogServerAddr parameter.

CVE-2017-18368 is a critical (CVSS 9.8) unauthenticated OS command injection (CWE-78) in the Remote System Log forwarding function of Zyxel P660HN-T1A (v1 and v2) and Billion 5200W-T routers distributed by Thailand ISP TrueOnline. An unauthenticated attacker who can reach the router's web management interface sends a crafted remote_host parameter to the ViewLog.asp page, with no credentials or user interaction required. Successful injection executes arbitrary operating-system commands on the device, giving the attacker full control of the router (e.g., botnet recruitment, traffic/DNS manipulation, or pivoting into the subscriber's LAN). Only TrueOnline-issued units of these models are affected, meaning Thai broadband subscribers deployed with this CPE. The flaw is in CISA's KEV catalog (added 2023-08-07), carries a 94.4% EPSS (100th percentile), and related reporting shows IoT botnets (e.g., Gafgyt campaigns against End-of-Life Zyxel routers and multi-exploit campaigns like RondoDox) actively targeting such devices.

Do: Update affected routers to the latest firmware available from Zyxel/Billion or via TrueOnline's ISP update process, noting these models are End-of-Life so hardware replacement is the durable fix. Until patched, restrict or disable WAN-side access to the router's web management interface (the flaw is reachable unauthenticated via ViewLog.asp) and audit devices for signs of botnet compromise. Per the CISA KEV required action, apply vendor mitigations or discontinue use of the product if mitigations are unavailable.

The mint function of a smart contract implementation for BillionRewardsToken, an Ethereum token, has an integer overflow that allows the owner of the contract to set the balance of an arbitrary user to any value.
