This updated advisory is a follow-up to the advisory update titled ICSA-21-238-03 Delta Electronics DIAEnergie (Update B) that was published March 22, 2022, on the ICS webpage at www.cisa.gov/ics.
Successful exploitation of these vulnerabilities could allow an attacker to retrieve passwords in cleartext, remotely execute code, cause a user to carry out an action unintentionally, or log in and use the device with administrative privileges.
The following versions of DIAEnergie are affected:
-------- Begin Update C Part 1 of 2 ---------
--------- End Update C Part 1 of 2 ---------
The affected product may allow an attacker to retrieve passwords in cleartext due to a weak hashing algorithm.
CVE-2021-33003 has been assigned to this vulnerability. A CVSS v3 base score of 5.5 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).
The affected product may allow an attacker to add a new administrative user without being authenticated or authorized, which may allow the attacker to log in and use the device with administrative privileges.
CVE-2021-32967 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
The affected product allows unrestricted file uploads, which may allow an attacker to remotely execute code.
CVE-2021-32955 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A Blind SQL injection vulnerability exists in the /DataHandler/Handler_CFG.ashx endpoint. The application does not properly validate the user-controlled value supplied through the parameter keyword before using it as part of an SQL query. A remote, unauthenticated attacker can exploit this issue to execute arbitrary code in the context of NT SERVICE\MSSQLSERVER.
CVE-2021-32983 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A Blind SQL injection vulnerability exists in the /DataHandler/HandlerEnergyType.ashx endpoint. The application does not properly validate the user-controlled value supplied through the parameter egyid before using it as part of an SQL query. A remote, unauthenticated attacker can exploit this issue to execute arbitrary code in the context of NT SERVICE\MSSQLSERVER.
CVE-2021-38390 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A Blind SQL injection vulnerability exists in the /DataHandler/AM/AM_Handler.ashx endpoint. The application does not properly validate the user-controlled value supplied through the parameter type before using it as part of an SQL query. A remote, unauthenticated attacker can exploit this issue to execute arbitrary code in the context of NT SERVICE\MSSQLSERVER.
CVE-2021-38391 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A Blind SQL injection vulnerability exists in the /DataHandler/HandlerAlarmGroup.ashx endpoint. The application does not properly validate the user-controlled value supplied through the parameter agid before using it as part of an SQL query. A remote, unauthenticated attacker can exploit this issue to execute arbitrary code in the context of NT SERVICE\MSSQLSERVER.
CVE-2021-38393 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
The affected product is vulnerable to cross-site request forgery, which may allow an attacker to cause a user to carry out an action unintentionally.
CVE-2021-32991 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N).
The affected product is vulnerable to a reflected cross-site scripting attack through error pages that are returned by “.NET Request.QueryString”.
CVE-2021-23228 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N).
The affected product is vulnerable to multiple cross-site scripting vulnerabilities when arbitrary code is injected into the parameter “name” of the script “HandlerEnergyType.ashx”.
CVE-2021-44544 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N).
The affected product is vulnerable to stored cross-site scripting when an unauthenticated user injects arbitrary code into the parameter “descr” of the script “DIAE_hierarchyHandler.ashx”.
CVE-2021-31558 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N).
The affected product is vulnerable to stored cross-site scripting when an unauthenticated user injects arbitrary code into the parameter “name” of the script “DIAE_HandlerAlarmGroup.ashx”.
CVE-2021-44471 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N).
The affected product is vulnerable to cleartext transmission as the web application runs by default on HTTP. This could allow an attacker to remotely read transmitted information between the client and product.
CVE-2022-0988 has been assigned to this vulnerability. A CVSS v3 base score of 7.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N).
