The ABB IDAL HTTP server CGI interface contains a URL that allows an unauthenticated attacker to bypass authentication and gain access to privileged functions. Specifically, /cgi/loginDefaultUser creates a session in an authenticated state and returns the session ID along with what may be the username and cleartext password of the user. An attacker can then supply an IDALToken value in a cookie, which will allow them to perform privileged operations such as restarting the service with /cgi/restart. A GET request to /cgi/loginDefaultUser may result in "1 #S_OK IDALToken=532c8632b86694f0232a68a0897a145c admin admin" or a similar response.

ICSA-19-178-01 — ABB PB610 Panel Builder 600

The ABB CP635 HMI component implements hidden administrative accounts used during the provisioning phase of the HMI interface. These credentials allow the provisioning tool Panel Builder 600 to flash a new interface and Tags (MODBUS coils) mapping to the HMI. These credentials are used over both HTTP(S) and FTP. There is no option to disable or change these undocumented credentials.CVE-2019-7225 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). The IDAL HTTP server CGI interface contains a URL, which allows an unauthenticated attacker to bypass authentication and gain access to privileged functions.CVE-2019-7226 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). The IDAL FTP server fails to ensure directory change requests do not change to locations outside of the root FTP directory. An authenticated attacker can simply traverse outside the server root directory by changing the directory.CVE-2019-7227 has been assigned to this vulnerability. A CVSS v3 base score of 7.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N). The IDAL HTTP server is vulnerable to memory corruption through insecure use of user supplied format strings. An attacker can abuse this functionality to bypass authentication or execute code on the server.CVE-2019-7228…
