CVE-2021-35683 is a critical vulnerability affecting Oracle Essbase Administration Services, specifically the EAS Console component. This vulnerability has a CVSS score of 9.9, indicating severe risk due to its potential to impact confidentiality, integrity, and availability. Attackers with low privileges can exploit this vulnerability through network access via HTTP, which could lead to a complete takeover of the affected services. Organizations that use Oracle Essbase must address this vulnerability promptly.
The vulnerability is classified as easily exploitable, meaning that attackers do not require high-level privileges or complex procedures to execute their attacks. Given the potential for significant impact and the simplicity of exploitation, organizations should prioritize patching immediately.
Oracle has released a patch for this vulnerability, and it is crucial for organizations to apply the updates to safeguard their systems. Failing to do so could expose sensitive data and critical infrastructure to severe risks.
Risk to organizations includes unauthorized access to sensitive data and potential service disruptions. The urgency to remediate this vulnerability cannot be overstated, especially considering its high severity and the likelihood of exploitation.
Vulnerability Details
The vulnerability description states that it is present in the Oracle Essbase Administration Services product. The affected version is prior to 11.1.2.4.047. The official description highlights how easily exploitable this vulnerability is, allowing a low privileged attacker to compromise Oracle Essbase Administration Services. Successful exploitation may have a cascading effect on additional products, potentially leading to severe consequences.
The CVSS 3.1 Base Score for this vulnerability is 9.9, indicating critical severity. The CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), which indicates that the vulnerability can be exploited over the network, requires low attack complexity, and does not require user interaction. The impact on confidentiality, integrity, and availability is rated as high.
Technical Analysis
The root cause of this vulnerability lies in the inadequate protections within the EAS Console component of Oracle Essbase. Attackers may leverage this vulnerability by sending crafted HTTP requests to the affected service, which could lead to unauthorized access and control over the administration services.
The attack vector is network-based, meaning that attackers do not need physical access to the target system to exploit this vulnerability. The attack complexity is low, requiring minimal effort and skills from the attacker. Moreover, the privileges required are low, allowing even those with limited access to exploit the vulnerability.
User interaction is not required, further increasing the risk as it allows attackers to execute their attacks without any action from the legitimate users. The impacts on confidentiality, integrity, and availability are rated high, indicating that a successful exploitation could result in severe damage to the organization.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is significant. Organizations that utilize Oracle Essbase must recognize that the potential for exploitation is high, given the ease of access and the critical nature of the services affected. The blast radius could encompass not only the Oracle Essbase Administration Services but also other interconnected systems and applications.
Given the CVSS score of 9.9, organizations should assess this vulnerability's urgency level as critical. Immediate remediation is necessary to mitigate the risks associated with this potential exploitation. Organizations should incorporate this vulnerability into their prioritization and patch management cycle.
