This vulnerability allows untrusted user input to be passed into SendStream.redirect(), leading to potential code execution. The CVSS score is 5.0, classifying it as medium severity. With an attack vector of network, attackers may exploit this vulnerability with high complexity and require user interaction. The urgency for organizations to address this vulnerability is moderate, as it can lead to malicious code execution if left unpatched.
Organizations should prioritize patching immediately. The issue affects all versions of the send library prior to version 0.19.0. Given the nature of the vulnerability, risk to organizations includes potential unauthorized code execution, which could result in further exploitation or data compromise.
As of now, there is no known exploit available for this vulnerability, but the potential for exploitation exists. Organizations using the send library are encouraged to review their implementations and apply the necessary patches.
Immediate action is crucial to prevent any unintended consequences from this vulnerability. Security teams should remain vigilant and monitor for any unusual activity that may indicate an attempt to exploit this weakness.
Vulnerability Details
The vulnerability in question is related to the send library used for streaming files as an HTTP response. Specifically, Send passes untrusted user input to SendStream.redirect(), which can execute untrusted code. This issue is patched in send version 0.19.0.
The CVSS score for this vulnerability is 5.0, indicating a medium severity level. The attack vector is classified as network, with high attack complexity, meaning it requires specific conditions to be exploited. Importantly, no privileges are required, but user interaction is necessary.
The vulnerability is associated with CWE-79, indicating a potential for code execution via user input. The vulnerability was published on September 10, 2024, and is classified as modified due to additional details being added post-publication.
Technical Analysis
The root cause of this vulnerability stems from the send library's handling of untrusted input. By passing untrusted data to SendStream.redirect(), the code execution can occur without proper validation, potentially allowing attackers to execute arbitrary code.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability over the internet. The attack complexity is classified as high, implying that an attacker must possess specific knowledge about the system and the conditions under which the exploit can be executed.
No privileges are required to exploit this vulnerability, which means any user can potentially leverage it. However, user interaction is required, indicating that an attacker must trick a user into triggering the exploit.
The exploitation can lead to low impacts on confidentiality, integrity, and availability. However, the potential for arbitrary code execution remains a significant concern for organizations using this library.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses risks to organizations utilizing the send library. The ability for untrusted user input to execute arbitrary code can lead to severe consequences, including unauthorized access to sensitive data and potential system compromise.
The blast radius for this vulnerability is concerning. If exploited, an attacker can potentially gain control over the server hosting the send library, leading to a cascading effect on the applications relying on it.
Given the CVSS score of 5.0, organizations should schedule remediation of this vulnerability promptly. With the potential for exploitation, it is critical to address this issue before it can lead to more severe incidents.

Affected Versions
The affected versions of the send library include all versions prior to 0.19.0. Organizations should ensure that they upgrade to the latest version to mitigate the risk associated with this vulnerability.
Mitigation & Remediation
To remediate this vulnerability, organizations should update to the patched version of the send library, which is 0.19.0 or later. If immediate patching is not possible, organizations should implement input validation to sanitize user inputs before passing them to SendStream.redirect().
Organizations may also consider performing a security assessment to evaluate their current application security posture. Regular security testing, such as penetration testing, can help identify similar vulnerabilities in their applications.
Detection Guidance
Monitoring application logs for unusual activity is essential. Look for indicators such as unexpected redirects or unauthorized access attempts. Behavioral anomalies in user interactions with the application may also signal attempts to exploit this vulnerability.
