The vulnerability identified as CVE-2021-44451 affects Apache Superset versions up to and including 1.3.2. This vulnerability allows for registered database connections password leak for authenticated users. The information can be accessed in a non-trivial manner, posing a significant risk to data confidentiality. The CVSS score for this vulnerability is 6.5, categorized as medium severity. Organizations utilizing Apache Superset should prioritize patching to mitigate potential risks.
Organizations need to recognize that the risk to organizations includes the unauthorized exposure of sensitive database credentials, which could lead to further exploitation if left unaddressed. Users are strongly encouraged to upgrade to Apache Superset version 1.4.0 or higher as a remediation step.
Currently, there are no known public exploits for this vulnerability, but it remains critical for organizations to stay vigilant. Organizations should assess their current deployment of Apache Superset and take necessary actions to protect their systems effectively.
Due to the medium severity of this vulnerability, organizations should address it in their priority patch cycle. The potential impact on confidentiality underscores the urgency of immediate remediation.
Vulnerability Details
The official description from the Apache community indicates that Apache Superset versions up to and including 1.3.2 have a flaw that allows authenticated users to leak passwords for registered database connections. The vulnerability is classified under CWE-522, which pertains to insufficiently protecting sensitive information.
The CVSS score of 6.5 suggests that the vulnerability has a medium impact, with a high confidentiality impact but no integrity or availability impact. It is advisable to upgrade to Apache Superset version 1.4.0 or higher to mitigate this issue. The vulnerability was published on February 1, 2022.
Technical Analysis
The root cause of this vulnerability lies in the handling of database connection credentials within Apache Superset. The attack vector is network-based, allowing remote attackers to exploit the flaw without requiring physical access to the server. The attack complexity is categorized as low, meaning that the vulnerability can be exploited easily without advanced skills.
The privileges required for exploitation are low, as attackers only need to be authenticated users. No user interaction is required, making it easier for attackers to leverage this vulnerability once they gain access to a valid user account.
The confidentiality impact is high, as sensitive credentials may be exposed, while integrity and availability are unaffected. Organizations should monitor their Superset instances closely and ensure that user access is limited to only necessary personnel.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to sensitive database information, which could lead to further attacks or data breaches. The potential blast radius is significant, particularly for organizations that rely on Apache Superset for business intelligence and data analytics. Attackers may leverage this vulnerability to gain insights into sensitive data.
Given the CVSS score of 6.5 and the impact on confidentiality, organizations should prioritize patching this vulnerability immediately. The high percentile score of 0.988970000 in the EPSS indicates a strong correlation with potential exploitation, reinforcing the importance of addressing this vulnerability as part of a robust security posture.
