SolarWinds Patches High-Severity Vulnerabilities

February 17, 2023

SolarWinds this week published multiple advisories describing high-severity vulnerabilities expected to be patched with a SolarWinds Platform update by the end of February. Out of a total of seven security defects, five are described as deserialization of untrusted data issues that could be exploited to achieve command execution, tracked as CVE-2023-23836, CVE-2022-47503, CVE-2022-47504, CVE-2022-47506, and CVE-2022-47507. SolarWinds considers the fifth bug, CVE-2022-38111, a medium-severity issue, albeit the consequences of successful exploitation are the same.

SolarWinds Platform 2023.1, which is expected to become available by the end of the month, resolves all vulnerabilities. Additionally, SolarWinds published information on a high-severity issue with Server & Application Monitor 2022.4, where Kerberos could not be used with NTLM. Hybrid Cloud Observability 2023.1, currently available as release candidate, resolves this flaw. As SolarWinds explains, “Customers who had configured their polling to occur via Kerberos did not expect NTLM Traffic on their environment, but since we were querying for data via IP address this prevented us from utilizing Kerberos.”

SolarWinds made no mention of any of these vulnerabilities being exploited in attacks. Customers are advised to update to the latest version as soon as it becomes available. As SolarWinds states, “This vulnerability allows a local adversary with authenticated account access to edit the default configuration, enabling the execution of arbitrary commands.”
