MEDIUM 5.5

DescriptionCVE.org

Versions of the package dom-iterator before 1.0.1 are vulnerable to Arbitrary Code Execution due to use of the Function constructor without complete input sanitization. Function generates a new function body and thus care must be given to ensure that the inputs to Function are not attacker-controlled. The risks involved are similar to that of allowing attacker-controlled input to reach eval.

AnalysisAI

Versions of the package dom-iterator before 1.0.1 are vulnerable to Arbitrary Code Execution due to use of the Function constructor without complete input sanitization. Rated medium severity (CVSS 5.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

Technical ContextAI

This vulnerability is classified as Code Injection (CWE-94), which allows attackers to inject and execute arbitrary code within the application. Versions of the package dom-iterator before 1.0.1 are vulnerable to Arbitrary Code Execution due to use of the Function constructor without complete input sanitization. Function generates a new function body and thus care must be given to ensure that the inputs to Function are not attacker-controlled. The risks involved are similar to that of allowing attacker-controlled input to reach eval. Affected products include: Matthewmueller Dom-Iterator. Version information: before 1.0.1.

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Never evaluate user-controlled input as code. Use sandboxing, disable dangerous functions, apply strict input validation.
