An unauthenticated update of public UI settings could be used by remote attackers to execute a stored cross-site scripting attack in the Rancher UI, in SUSE Rancher 2.15 before 2.15.2, 2.14 before 2.14.6, 2.13 before 2.13.10, 2.12 before 2.12.14 and 2.11 before 2.11.18.
This vulnerability (CWE-79) in SUSE Rancher allows unauthenticated remote attackers to perform a stored cross-site scripting attack by updating public UI settings. The flaw exists in Rancher versions 2.15 before 2.15.2, 2.14 before 2.14.6, 2.13 before 2.13.10, 2.12 before 2.12.14, and 2.11 before 2.11.18. Exploitation could lead to execution of arbitrary scripts in the context of the Rancher UI, impacting confidentiality, integrity, and availability.
Successful exploitation allows remote attackers to execute arbitrary scripts in the Rancher UI without authentication, potentially leading to full compromise of the UI session, data theft, or manipulation of Rancher management functions. The CVSS score of 9.6 reflects critical impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Fixed versions are available for all affected branches: upgrade to Rancher 2.15.2 or later, 2.14.6 or later, 2.13.10 or later, 2.12.14 or later, and 2.11.18 or later. Applying these official fixes will remediate the vulnerability.
