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.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2023-10-18 21:15:00","updated_at":"2023-10-30 13:37:00"},"problem_types":["CWE-1333"],"metrics":[],"references":[{"url":"https://github.com/DedSecInside/TorBot/security/advisories/GHSA-72qw-p7hh-m3ff","name":"https://github.com/DedSecInside/TorBot/security/advisories/GHSA-72qw-p7hh-m3ff","refsource":"MISC","tags":[],"title":"Inefficient Regular Expression Complexity in validate_link · Advisory · DedSecInside/TorBot · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"429"},{"url":"https://github.com/DedSecInside/TorBot/commit/ef6e06bc7785355b1701d5524eb4550441086ac4","name":"https://github.com/DedSecInside/TorBot/commit/ef6e06bc7785355b1701d5524eb4550441086ac4","refsource":"MISC","tags":[],"title":"remove unused validators file · DedSecInside/TorBot@ef6e06b · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"429"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-45813","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45813","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"45813","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"torbot_project","cpe5":"torbot","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2023","cve_id":"45813","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"validators_project","cpe5":"validators","cpe6":"0.11.0","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"python","cpe12":"*","cpe13":"*"},{"cve_year":"2023","cve_id":"45813","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"validators_project","cpe5":"validators","cpe6":"0.20.0","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"python","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[{"cve":"CVE-2023-45813","qid":"995663","title":"Python (Pip) Security Update for torbot (GHSA-72qw-p7hh-m3ff)"}]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-45813","ASSIGNER":"security-advisories@github.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"Torbot is an open source tor network intelligence tool.
