Successful exploitation of these vulnerabilities may allow unauthenticated attackers to perform arbitrary command execution, SQL injection, or remote code execution.
Rockwell Automation reports these vulnerabilities affects the following products:
A deserialization vulnerability exists in how the AosService.rem service in FactoryTalk AssetCentre verifies serialized data. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary commands in FactoryTalk AssetCentre.
CVE-2021-27462 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
A deserialization vulnerability exists in how the ArchiveService.rem service in FactoryTalk AssetCentre verifies serialized data. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary commands in FactoryTalk AssetCentre.
CVE-2021-27466 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
A deserialization vulnerability exists in how the LogService.rem service in FactoryTalk AssetCentre verifies serialized data. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary commands in FactoryTalk AssetCentre.
CVE-2021-27470 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
FactoryTalk AssetCentre does not properly restrict all functions relating to IIS remoting services. This vulnerability may allow a remote, unauthenticated attacker to modify sensitive data in FactoryTalk AssetCentre.
CVE-2021-27474 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
A vulnerability exists in the SaveConfigFile function of the RACompare Service, which may allow for OS command injection. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary commands in FactoryTalk AssetCentre.
CVE-2021-27476 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
A vulnerability exists in the RunSearch function of SearchService service, which may allow for the execution of remote unauthenticated arbitrary SQL statements.
CVE-2021-27472 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
The AosService.rem service exposes functions lacking proper authentication. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary SQL statements.
CVE-2021-27468 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
The ArchiveService.rem service exposes functions lacking proper authentication. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary SQL statements.
CVE-2021-27464 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
FactoryTalk AssetCentre components contain .NET remoting endpoints that deserialize untrusted data without sufficiently verifying that the resulting data will be valid. This vulnerability may allow a remote, unauthenticated attacker to gain full access to the FactoryTalk AssetCentre main server and all agent machines.
CVE-2021-27460 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
Sharon Brizinov and Amir Preminger of Claroty reported these vulnerabilities to Rockwell Automation.
Rockwell Automation encourages users of the affected versions of FactoryTalk AssetCentre to update to AssetCentre v11 (or above) to addresses these vulnerabilities. For more information about these vulnerabilities and mitigations please see Rockwell Automationβs publication KnowledgeBase ID: PN1559
As an additional mitigation, Rockwell Automation encourages users who are unable to upgrade or are concerned about unauthorized client connections to use built in security features found within FactoryTalk AssetCentre. Users should follow guidance found in QA46277. IPsec would minimize exposure to unauthorized clients and has been tested in FactoryTalk AssetCentre v9-v11
Rockwell Automation recommends the following software/PC-based mitigation strategies:
Rockwell Automation recommends the following general mitigations:
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01BβTargeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities.
