Описание
Underscore.js is a utility-belt library for JavaScript. Prior to 1.13.8, the _.flatten and _.isEqual functions use recursion without a depth limit. Under very specific conditions, detailed below, an attacker could exploit this in a Denial of Service (DoS) attack by triggering a stack overflow. Untrusted input must be used to create a recursive datastructure, for example using JSON.parse, with no enforced depth limit. The datastructure thus created must be passed to _.flatten or _.isEqual. In the case of _.flatten, the vulnerability can only be exploited if it is possible for a remote client to prepare a datastructure that consists of arrays at all levels AND if no finite depth limit is passed as the second argument to _.flatten. In the case of _.isEqual, the vulnerability can only be exploited if there exists a code path in which two distinct datastructures that were submitted by the same remote client are compared using _.isEqual. For example, if a client submits data that are stored in a database, and the same client can later submit another datastructure that is then compared to the data that were saved in the database previously, OR if a client submits a single request, but its data are parsed twice, creating two non-identical but equivalent datastructures that are then compared. Exceptions originating from the call to _.flatten or _.isEqual, as a result of a stack overflow, are not being caught. This vulnerability is fixed in 1.13.8.
A flaw was found in Underscore.js, a JavaScript utility library. This vulnerability allows a remote attacker to trigger a Denial of Service (DoS) attack by providing specially crafted recursive data structures. When these structures are processed by the _.flatten or _.isEqual functions, which lack a depth limit for recursion, a stack overflow occurs. This can make the application unavailable to legitimate users.
Меры по смягчению последствий
To mitigate this issue, applications utilizing Underscore.js should ensure that any processing of untrusted, recursively structured data with _.flatten or _.isEqual explicitly enforces a finite depth limit. Review application code to identify and modify calls to these functions, adding appropriate depth parameters to prevent stack overflow conditions. Additionally, input validation should be implemented to sanitize untrusted data before it is processed by Underscore.js functions.
