CVSS: 5.3EPSS: 0%CPEs: 6EXPL: 0CVE-2019-15987 – Cisco WebEx Centers Username Enumeration Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2019-15987
A vulnerability in web interface of the Cisco Webex Event Center, Cisco Webex Meeting Center, Cisco Webex Support Center, and Cisco Webex Training Center could allow an unauthenticated, remote attacker to guess account usernames. The vulnerability is due to missing CAPTCHA protection in certain URLs. An attacker could exploit this vulnerability by sending a crafted request to the web interface. A successful exploit could allow the attacker to know if a given username is valid and find the real name of the user. Una vulnerabilidad en la interfaz web de Cisco Webex Event Center, Cisco Webex Meeting Center, Cisco Webex Support Center y Cisco Webex Training Center, podría permitir a un atacante remoto no autenticado adivinar los nombres de usuario de las cuentas. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191120-webex-centers-infodis • CWE-287: Improper Authentication •
CVSS: 7.8EPSS: 74%CPEs: 127EXPL: 0CVE-2018-5390 – Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service
https://notcve.org/view.php?id=CVE-2018-5390
Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. El kernel de Linux en versiones 4.9 y siguientes pueden forzarse a realizar llamadas muy caras a tcp_collapse_ofo_queue() y tcp_prune_ofo_queue() para cada paquete entrante, lo que puede conducir a una denegación de servicio. A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20181031-02-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/104976 http://www.securitytracker.com/id/1041424 http://www.securitytracker.com/id/1041434 https://access.redhat.co • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 0CVE-2018-0379 – Cisco WebEx Recorder and Player ATDL2006 Use-After-Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2018-0379
Multiple vulnerabilities exist in the Cisco Webex Network Recording Player for Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. An attacker could exploit these vulnerabilities by providing a user with a malicious .arf or .wrf file via email or URL and convincing the user to launch the file in the Webex recording players. Exploitation of these vulnerabilities could allow arbitrary code execution on the system of a targeted user. These vulnerabilities affect ARF and WRF recording players available from Cisco Webex Meetings Suite sites, Cisco Webex Meetings Online sites, and Cisco Webex Meetings Server. Cisco Bug IDs: CSCvi02621, CSCvi02965, CSCvi63329, CSCvi63333, CSCvi63335, CSCvi63374, CSCvi63376, CSCvi63377, CSCvi63391, CSCvi63392, CSCvi63396, CSCvi63495, CSCvi63497, CSCvi63498, CSCvi82684, CSCvi82700, CSCvi82705, CSCvi82725, CSCvi82737, CSCvi82742, CSCvi82760, CSCvi82771, CSCvj51284, CSCvj51294. • http://www.securityfocus.com/bid/104853 http://www.securitytracker.com/id/1041347 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180718-webex-rce • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

A vulnerability in the Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files could allow an unauthenticated, remote attacker to execute arbitrary code on the system of a targeted user. An attacker could exploit this vulnerability by sending the user a link or email attachment with a malicious ARF file and persuading the user to follow the link or open the file. Successful exploitation could allow the attacker to execute arbitrary code on the user's system. This vulnerability affects Cisco WebEx Business Suite meeting sites, Cisco WebEx Meetings sites, Cisco WebEx Meetings Server, and Cisco WebEx ARF players. The following client builds of Cisco WebEx Business Suite (WBS31 and WBS32), Cisco WebEx Meetings, and Cisco WebEx Meetings Server are affected: Cisco WebEx Business Suite (WBS31) client builds prior to T31.23.4, Cisco WebEx Business Suite (WBS32) client builds prior to T32.12, Cisco WebEx Meetings with client builds prior to T32.12, Cisco WebEx Meeting Server builds prior to 3.0 Patch 1. • http://www.securityfocus.com/bid/104073 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180502-war • CWE-20: Improper Input Validation •
