CVE-2024-48949 is a critical vulnerability found in the Indutny Elliptic package, specifically within the verify function located in lib/elliptic/eddsa/index.js. This vulnerability allows attackers to bypass crucial validation checks, potentially leading to unauthorized access and manipulation of sensitive data. With a CVSS score of 9.1, the severity of this vulnerability demands immediate attention from organizations utilizing this library in their applications.
The risk to organizations includes significant impacts on data integrity and confidentiality due to the omission of critical validation checks, specifically the validation for signature values. As a result, attackers may exploit this flaw to forge signatures, compromising the security of cryptographic operations performed by the affected library.
Currently, there are no known public exploits available for this vulnerability. However, given its critical nature, organizations must prioritize patching to protect their systems from potential exploits that may arise.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The latest version of the Indutny Elliptic package, 6.5.6, addresses this issue, and upgrading to this version is essential for safeguarding applications.
Vulnerability Details
The vulnerability is characterized by the failure of the verification function to validate the signature values adequately. Specifically, the absence of checks for "sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()" allows for the possibility of signature forgery.
The CVSS score of 9.1 categorizes this vulnerability as critical, indicating a high level of risk. This score reflects a network attack vector, low complexity, no privileges required, and no user interaction necessary, which amplifies the urgency for organizations to address this vulnerability.
Affected products include the Indutny Elliptic package versions prior to 6.5.6. This vulnerability was published on October 10, 2024.
Technical Analysis
The root cause of CVE-2024-48949 lies in the verification logic of the Elliptic package. The vulnerability stems from improper validation of signature values, which can lead to both integrity and confidentiality impacts. Attackers may leverage this vulnerability through a network attack vector, exploiting it without the need for any privileges or user interaction.
The attack complexity for this vulnerability is low, making it accessible for potential attackers. With high confidentiality and integrity impacts, organizations using the affected versions of the Elliptic package are at significant risk.
Risk & Impact Analysis
Real-world deployment of the vulnerable Indutny Elliptic package can lead to severe consequences, including unauthorized access to sensitive data and potential data breaches. This vulnerability could serve as a gateway for attackers to compromise systems that rely on cryptographic operations.
The urgency for organizations to address this vulnerability is underscored by its critical CVSS score and the potential for exploitation. Organizations must assess their exposure to this vulnerability and implement necessary mitigations to protect their assets.
