CVE-2024-0569 is a medium severity information disclosure flaw in Totolink T8, scored CVSS 4.3. The record lists Totolink T8 firmware 4.1.5cu.833_20220905. The record says upgrading to 4.1.5cu.862_B20230228 addresses the issue. Use the steps below to confirm your exposure and plan the fix.
What's affected
The record lists Totolink T8 firmware 4.1.5cu.833_20220905. The getSysStatusCfg function in /cgi-bin/cstecgi.cgi can disclose the ssid and key values.
The CVSS vector in the record is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N, with a base score of 4.3 (Medium). KEV status: not listed in the record.
Fixed version: The record says upgrading to 4.1.5cu.862_B20230228 addresses the issue.
How to check if you're exposed
Log in to the router admin page and read the firmware version on the status or system page, then compare it with the version named in the record. Also check whether the admin page is reachable from the WAN side.
The request path /cgi-bin/cstecgi.cgi is the common web handler on these devices, so any exposure of the admin interface to the internet is worth closing regardless of the firmware version.
What to do now
- Turn off remote administration from the WAN side and limit the admin page to a trusted management network.
- Check the vendor site for the firmware version named in the advisory and install it where one exists.
- If the vendor offers no fix, plan to replace the device or place it behind a firewall that blocks access to its web interface.
- Change administrator credentials and wireless keys if the device was ever exposed.
Why it matters
CWE-200 describes this class. Exposure of sensitive information means a function returns data to a caller who should not see it. On a router that data can include network names and keys. Even a medium score deserves attention when the leaked values are credentials.
CWE-862 describes this class. Missing authorization means a function runs without checking whether the caller is allowed to use it. The request is accepted because nothing asks the question. Every handler on a device web interface needs its own authorization check, not just the login page.
The record notes that an exploit has been disclosed publicly, which shortens the time between disclosure and scanning by others. The record does not say the flaw is exploited in the wild, and it is not in the CISA KEV catalog.
Safeguard Gold keeps a page for this CVE at gold.safeguard.sh, and the free in-browser dependency scan can show whether software you build bundles related components.
Quick check
Is CVE-2024-0569 exploited in the wild?
The record's KEV flag is false, and none of the pages I fetched said otherwise. That is not proof of safety, so still patch or restrict access.
What if the vendor never ships a fix?
Limit the admin interface to a trusted network, disable remote management, and plan to replace the device.
