Cisco has warned of a critical security flaw in SPA112 2-port phone adapters that it said could be exploited by a remote attacker to execute arbitrary code on affected devices.

The issue, tracked as CVE-2023-20126, has a score of 9.8 out of a maximum of 10 in the CVSS scoring system. The company credited DBappSecurity’s Catalpa for reporting the flaw.

The product in question allows analog telephones and fax machines to be connected to a VoIP service provider without the need for an upgrade.

“This vulnerability is due to a missing authentication process within the firmware update function,” the company said in a bulletin.

“An attacker could exploit this vulnerability by updating an affected device to an engineered version of the firmware. A successful exploit could allow an attacker to execute arbitrary code on the affected device with full privileges.”

Despite the severity of the flaw, the networking equipment maker said it does not intend to release fixes due to the fact that the devices have reached the end-of-life (EoL) state as of 1 June 2020.

Instead, it recommends that users migrate to a Cisco ATA 190 series analog phone adapter, which will receive its latest update on March 31, 2024. There is no evidence that the flaw has been maliciously exploited in the wild .
