A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The application, after a successful login, sets the session cookie on the browser via client-side JavaScript code, without applying any security attributes (such as “Secure”, “HttpOnly”, or “SameSite”). Any attempts to browse the application via unencrypted HTTP protocol would lead to the transmission of all his/her session cookies in plaintext through the network. An attacker could then be able to sniff the network and capture sensitive information.

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The login functionality of the application does not employ any countermeasures against Password Spraying attacks or Credential Stuffing attacks. An attacker could obtain a list of valid usernames on the device by exploiting the issue and then perform a precise Password Spraying or Credential Stuffing attack in order to obtain access to at least one account.

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The login functionality of the application fails to normalize the response times of login attempts performed with wrong usernames with the ones executed with correct usernames. A remote unauthenticated attacker could exploit this side-channel information to perform a username enumeration attack and identify valid usernames.

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The web application returns an AuthToken that does not expire at the defined auto logoff delay timeout. An attacker could be able to capture this token and re-use old session credentials or session IDs for authorization.

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The web application stores the PBKDF2 derived key of users passwords with a low iteration count. An attacker with user profile access privilege can retrieve the stored password hashes of other accounts and then successfully perform an offline cracking attack and recover the plaintext passwords of other users.

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The web application fails to enforce an upper bound to the cost factor of the PBKDF2 derived key during the creation or update of an account. An attacker with the user profile access privilege could cause a denial of service (DoS) condition through CPU consumption by setting a PBKDF2 derived key with a remarkably high cost effort and then attempting a login to the so-modified account.

A vulnerability has been identified in Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The “addCell” JavaScript function fails to properly sanitize user-controllable input before including it into the generated XML body of the XLS report document, such that it is possible to inject arbitrary content (e.g., XML tags) into the generated file. An attacker with restricted privileges, by poisoning any of the content used to generate XLS reports, could be able to leverage the application to deliver malicious files against higher-privileged users and obtain Remote Code Execution (RCE) against the administrator’s workstation.

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). When the controller receives a specific BACnet protocol packet, an exception causes the BACnet communication function to go into a “out of work” state and could result in the controller going into a “factory reset” state.
