The vulnerability is due to improper handling of orphaned t-shell sessions. An attacker could exploit this vulnerability by opening several Secure Shell (SSH) sessions with the affected system. An exploit could allow the attacker to consume available memory; therefore, the affected system may become unreachable and unable to function properly. A hard reboot is needed to restore complete functionality. Cisco has confirmed the vulnerability in a Security Notice and software updates are available. To exploit this vulnerability, the attacker must authenticate to a targeted system. This access requirement limits the possibility of a successful exploit. Customers are advised to review the bug report in the \"Vendor Announcements\" section for a current list of affected versions. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.","severity":"Medium","published_at":"2013-05-29T18:39:54Z","updated_at":"2013-05-29T18:39:54Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20130529-CVE-2013-1246","csaf_url":"https://sec.cloudapps.cisco.com/security/center/contentjson/CiscoSecurityAdvisory/Cisco-SA-20130529-CVE-2013-1246/csaf/Cisco-SA-20130529-CVE-2013-1246.json","exposure_verdict":"not_assessed","verdict_reason":"Public evidence does not evaluate exact release, platform, enabled features, configuration, compensating controls, or live exposure."},"freshness":{"last_source_refreshed_at":"2026-07-21T05:16:34Z","latest_source_refresh_at":"2026-07-21T05:16:34Z","oldest_source_refresh_at":"2026-07-21T03:00:03Z","all_sources_fresh":true,"sources":[{"source":"cisco_advisories","label":"Cisco advisories","last_success_at":"2026-07-21T03:00:03Z","stale":false},{"source":"cisco_csaf","label":"Cisco CSAF","last_success_at":"2026-07-21T05:14:24Z","stale":false},{"source":"nvd_cves","label":"NVD CVEs","last_success_at":"2026-07-21T05:16:30Z","stale":false},{"source":"cisa_kev","label":"CISA KEV","last_success_at":"2026-07-21T05:16:31Z","stale":false},{"source":"first_epss","label":"EPSS","last_success_at":"2026-07-21T05:16:34Z","stale":false}]},"summary":{"cve_count":1,"visible_product_count":1,"public_evidence_count":1,"kev_count":0,"highest_epss":0.01664},"cves":[{"id":"CVE-2013-1246","kev":false,"epss":{"score":0.01664,"percentile":0.74102,"score_date":"2026-07-19","updated_at":"2026-07-20T05:46:47Z"}}],"public_evidence":[{"product":{"name":"Cisco TelePresence System Software","slug":"cisco-telepresence-system-software","vendor":"Cisco"},"cve":{"id":"CVE-2013-1246"},"evidence_type":"structured_affected","evidence_label":{"scope":"CSAF product evidence","label":"product_status known affected"},"evidence_source":"Cisco CSAF","source":"Cisco CSAF","source_document_fetched_at":"2026-07-20T04:58:09Z","csaf_status":"known_affected","csaf_product_status":"known_affected","csaf_product_status_path":"vulnerabilities[].product_status.known_affected","raw_product_name":"Cisco TelePresence System Software","exposure_verdict":"not_assessed","verdict_reason":"Public evidence does not evaluate exact release, platform, enabled features, configuration, compensating controls, or live exposure.","exposure_verdict_reason":"Public evidence does not evaluate exact release, platform, enabled features, configuration, compensating controls, or live exposure.","kev":false,"epss":{"score":0.01664,"score_date":"2026-07-19","updated_at":"2026-07-20T05:46:47Z"},"published_at":"2013-05-29T18:39:54Z","updated_at":"2013-05-29T18:39:54Z","advisory_updated_at":"2013-05-29T18:39:54Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20130529-CVE-2013-1246","row_display_order":1}]}
