A CWE-798: Use of Hard-coded Credentials vulnerability exists that could result in information disclosure. If an attacker were to obtain the SSH cryptographic key for the device and take active control of the local operational network connected to the product they could potentially observe and manipulate traffic associated with product configuration. Affected Product: Easergy P5 (All firmware versions prior to V01.401.101)

If an attacker were to obtain the SSH cryptographic key for the device and take active control of the local operational network connected to this product, they could observe and manipulate traffic associated with product configuration. This could result in information disclosure. CVE-2022-22722 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H). A buffer copy without checking size of input vulnerability exists in Easergy P5 devices that could lead to a buffer overflow, causing program crashes and arbitrary code execution when specially crafted packets are sent to the device over the network. Protection functions and tripping functions via GOOSE can be impacted. CVE-2022-22723 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). A buffer copy without checking size of input vulnerability exists in Easergy P3 devices that could lead to a buffer overflow, causing program crashes and arbitrary code execution when specially crafted packets are sent to the device over the network. Protection functions and tripping functions via GOOSE can be impacted. CVE-2022-22725 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). An Improper Input Validation vulnerability exists in Easergy P5…

Schneider Electric is aware of multiple vulnerabilities in its Easergy P5 product line. The Easergy P5 is a medium voltage protection relay. Failure to apply the mitigations or remediations provided below may risk disclosure of the device credentials, denial of service, device reboot, or at attacker gaining full control of the relay. This could result in loss of protection to your electrical network.
