Summary

Duplicate Advisory: ReDos vulnerability of XMLFeedSpider

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-cc65-xxvf-f7r9. This link is maintained to preserve external references.

Original Description

Parts of the Scrapy API were found to be vulnerable to a ReDoS attack. Handling a malicious response could cause extreme CPU and memory usage during the parsing of its content, due to the use of vulnerable regular expressions for that parsing.

Severity ?

7.5 (High)

CVE-2024-1892 (GCVE-0-2024-1892)

Vulnerability from cvelistv5 – Published: 2024-02-28 00:00 – Updated: 2024-08-11 14:28

Summary

A Regular Expression Denial of Service (ReDoS) vulnerability exists in the XMLFeedSpider class of the scrapy/scrapy project, specifically in the parsing of XML content. By crafting malicious XML content that exploits inefficient regular expression complexity used in the parsing process, an attacker can cause a denial-of-service (DoS) condition. This vulnerability allows for the system to hang and consume significant resources, potentially rendering services that utilize Scrapy for XML processing unresponsive.

Severity ?

7.5 (High)
