{"id":"CVE-2023-45813","state":"PUBLISHED","title":"Inefficient Regular Expression Complexity in TorBot","description":"Torbot is an open source tor network intelligence tool. In affected versions the `torbot.modules.validators.validate_link function` uses the python-validators URL validation regex. This particular regular expression has an exponential complexity which allows an attacker to cause an application crash using a well-crafted argument. An attacker can use a well-crafted URL argument to exploit the vulnerability in the regular expression and cause a Denial of Service on the system. The validators file has been removed in version 4.0.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.","publishedAt":"2023-10-18T20:26:44.531Z","updatedAt":"2024-09-13T14:39:25.852Z","severity":{"score":4.6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["DedSecInside TorBot"],"affected":[{"vendor":"DedSecInside","product":"TorBot","versions":[{"version":"< 4.0.0","status":"affected"}]}],"references":["https://github.com/DedSecInside/TorBot/security/advisories/GHSA-72qw-p7hh-m3ff","https://github.com/DedSecInside/TorBot/commit/ef6e06bc7785355b1701d5524eb4550441086ac4"],"weaknesses":["CWE-1333"],"ingestedAt":"2026-10-29T20:06:24.729Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/45xxx/CVE-2023-45813.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-45813","state":"PUBLISHED","datePublished":"2023-10-18T20:26:44.531Z","dateUpdated":"2024-09-13T14:39:25.852Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-10-13T12:00:50.437Z"},"containers":{"cna":{"title":"Inefficient Regular Expression Complexity in TorBot","descriptions":[{"lang":"en","value":"Torbot is an open source tor network intelligence tool.
