ICSA-22-132-10: Siemens Desigo PXC and DXR Devices
The addCell JavaScript function fails to properly sanitize user-controllable input before including it into the generated XML body of the XLS report document as it is possible to inject arbitrary content (e.g., XML tags) into the generated file. An attacker with restricted privileges could corrupt the content used to generate XLS reports to leverage the application to deliver malicious files against higher-privileged users and obtain remote code execution (RCE) against the administrator 's workstation.CVE-2022-24039 has been assigned to this vulnerability. A CVSS v3 base score of 9.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H). 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 condition through CPU consumption by setting a PBKDF2 derived key with a high-cost effort, followed by a login attempt to the modified account.CVE-2022-24040 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:N/A:H). The web application stores the PBKDF2 derived key of user 's 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.CVE-2022-24041 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:H/I:N/A:N). The web application returns an AuthToken that does not expire at the defined auto logoff delay timeout. An attacker could capture this token and re-use old session credentials or session IDs for authorization.CVE-2022-24042 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). 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.CVE-2022-24043 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). The login functionality of the application does not employ countermeasures against password spraying attacks or credential stuffing attacks. An attacker could obtain a list of valid usernames on the device and use that list to perform a precise password spraying or credential stuffing attack to obtain access to at least one account.CVE-2022-24044 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:H/I:N/A:N). Following a successful login, the application sets the session cookie on the browser via client-side JavaScript code without applying 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 session cookies in plaintext through the network. An attacker could then sniff the network and capture sensitive information.CVE-2022-24045 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:H/I:N/A:N). 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.CVE-2021-41545 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:N/A:H).
