CVE-2022-27499 is a low-severity vulnerability that affects the Intel SGX SDK. This vulnerability allows for a premature release of resource during the expected lifetime, which may lead to potential information disclosure if exploited by a privileged user. The CVSS score for this vulnerability is 2.5, indicating its low impact on the system's integrity and availability.
The vulnerability was published on November 11, 2022, and its status has been modified. Organizations utilizing affected versions of the Intel SGX SDK should be aware of the risks associated with this vulnerability, particularly in environments where local access can be gained by privileged users.
Given the potential for information disclosure, organizations should prioritize patching this vulnerability. Although it has a low severity rating, the implications of information disclosure must not be underestimated, especially in sensitive environments.
The urgency for defenders is moderate, as the exploitability of this vulnerability is low. However, organizations should still assess their exposure and apply necessary patches to mitigate risks associated with CVE-2022-27499.
Vulnerability Details
The official description of CVE-2022-27499 states that it allows for a premature release of resources during the expected lifetime in the Intel SGX SDK software. The primary vulnerability type is classified under CWE-672, indicating a resource management issue.
The CVSS score is officially noted as 2.5, which indicates a low severity classification. The attack vector is local, with a high attack complexity and a requirement for high privileges. There is no user interaction required, and the confidentiality impact is rated as low, while integrity and availability impacts are none.
The vulnerability affects the Intel SGX SDK on both Windows and Linux platforms. The versions affected are all prior to version 2.17.100.1 for Windows and 2.18.100.1 for Linux.
Technical Analysis
The root cause of this vulnerability stems from the improper handling of resource lifecycles within the Intel SGX SDK. Specifically, the premature release of resources allows a privileged user to potentially gain access to sensitive information that should be protected.
The attack vector for this vulnerability is local, meaning an attacker must have physical or logical access to the affected system. The attack complexity is rated as high, indicating that exploiting this vulnerability requires specific conditions or knowledge. Since high privileges are required to exploit this vulnerability, it limits the potential attack surface.
User interaction is not required for exploitation. The confidentiality impact is low as the potential information disclosure is limited, while the integrity and availability impacts are none.
Risk & Impact Analysis
Organizations utilizing the affected versions of the Intel SGX SDK must recognize the moderate urgency associated with this vulnerability. The risk includes potential information disclosure which could have consequences for sensitive data handled by the SDK.
The blast radius is limited due to the requirement for local access and high privileges. However, the presence of this vulnerability in a broader deployment could lead to significant risks if exploited by malicious insiders or compromised accounts.
Organizations should evaluate their exposure based on their deployment and usage patterns of the Intel SGX SDK. Although the risk is classified as low, it is crucial to prioritize remediation as part of the overall security strategy.
Exploitation Status
Signal | Status |
|---|---|
