D-Hyperlink is warning that 4 distant code execution (RCE) flaws impacting all {hardware} and firmware variations of its DIR-846W router won’t be mounted because the merchandise are now not supported.
The 4 RCE flaws, three of that are rated vital and don’t require authentication, had been found by security researcher yali-1002, who launched minimal particulars of their GitHub repository.
The researcher printed the knowledge on August 27, 2024, however has withheld the publication of proof-of-concept (PoC) exploits for now.
The failings are summarized as follows:
- CVE-2024-41622: Distant Command Execution (RCE) vulnerability through the tomography_ping_address parameter within the /HNAP1/ interface. (CVSS v3 rating: 9.8 “vital”)
- CVE-2024-44340: RCE vulnerability through the smartqos_express_devices and smartqos_normal_devices parameters in SetSmartQoSSettings (authenticated entry requirement reduces the CVSS v3 rating to eight.8 “excessive”).
- CVE-2024-44341: RCE vulnerability through the lan(0)_dhcps_staticlist parameter, exploitable by means of a crafted POST request. (CVSS v3 rating: 9.8 “vital”)
- CVE-2024-44342: RCE vulnerability through the wl(0).(0)_ssid parameter. (CVSS v3 rating: 9.8 “vital”)
Although D-Hyperlink acknowledged the security issues and their severity, it famous that they fall beneath its normal end-of-life/end-of-support insurance policies, that means there will likely be no security updates to handle them.
“As a normal coverage, when merchandise attain EOS/EOL, they will now not be supported, and all firmware growth for these merchandise stop,” reads D-Hyperlink’s announcement.
