CVE-2024-20414 1 Cisco 2 Ios, Ios Xe 2024-10-02 N/A 6.5 MEDIUM
A vulnerability in the web UI feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system through the web UI. This vulnerability is due to incorrectly accepting configuration changes through the HTTP GET method. An attacker could exploit this vulnerability by persuading a currently authenticated administrator to follow a crafted link. A successful exploit could allow the attacker to change the configuration of the affected device.
CVE-2006-3906 1 Cisco 21 Adaptive Security Appliance Software, Ios, Pix Asa Ids and 18 more 2024-07-02 5.0 MEDIUM N/A
Internet Key Exchange (IKE) version 1 protocol, as implemented on Cisco IOS, VPN 3000 Concentrators, and PIX firewalls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of IKE Phase-1 packets that exceed the session expiration rate. NOTE: it has been argued that this is due to a design weakness of the IKE version 1 protocol, in which case other vendors and implementations would also be affected.
CVE-2005-3669 1 Cisco 8 Adaptive Security Appliance Software, Firewall Services Module, Ios and 5 more 2024-07-02 5.0 MEDIUM N/A
Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in multiple Cisco products allow remote attackers to cause a denial of service (device reset) via certain malformed IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Cisco advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.

CVE-2019-1738 1 Cisco 2 Ios, Ios Xe 2024-03-04 7.8 HIGH 7.5 HIGH
A vulnerability in the Network-Based Application Recognition (NBAR) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. This vulnerability is due to a parsing issue on DNS packets. An attacker could exploit these vulnerabilities by sending crafted DNS packets through routers that are running an affected version and have NBAR enabled. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition.
CVE-2021-34699 1 Cisco 2 Ios, Ios Xe 2024-03-04 6.8 MEDIUM 7.7 HIGH
A vulnerability in the TrustSec CLI parser of Cisco IOS and Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload. This vulnerability is due to an improper interaction between the web UI and the CLI parser. An attacker could exploit this vulnerability by requesting a particular CLI command to be run through the web UI. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition.
CVE-2019-1739 1 Cisco 2 Ios, Ios Xe 2024-03-04 7.8 HIGH 7.5 HIGH
A vulnerability in the Network-Based Application Recognition (NBAR) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. This vulnerability is due to a parsing issue on DNS packets. An attacker could exploit this vulnerability by sending crafted DNS packets through routers that are running an affected version and have NBAR enabled.

CVE-2019-1757 1 Cisco 2 Ios, Ios Xe 2024-03-04 4.3 MEDIUM 5.9 MEDIUM
A vulnerability in the Cisco Smart Call Home feature of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to gain unauthorized read access to sensitive data using an invalid certificate. The vulnerability is due to insufficient certificate validation by the affected software. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt confidential information on user connections to the affected software.
CVE-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2024-02-15 5.0 MEDIUM N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-2002-1706 1 Cisco 3 Ios, Ubr7100, Ubr7200 2024-02-08 5.0 MEDIUM 7.5 HIGH
Cisco IOS software 11.3 through 12.2 running on Cisco uBR7200 and uBR7100 series Universal Broadband Routers allows remote attackers to modify Data Over Cable Service Interface Specification (DOCSIS) settings via a DOCSIS file without a Message Integrity Check (MIC) signature, which is approved by the router.
CVE-2021-34705 1 Cisco 2 Ios, Ios Xe 2024-02-07 4.3 MEDIUM 5.3 MEDIUM
A vulnerability in the Voice Telephony Service Provider (VTSP) service of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass configured destination patterns and dial arbitrary numbers.

An attacker could exploit this vulnerability by sending a malformed dial string to an affected device via either the ISDN protocol or SIP. A successful exploit could allow the attacker to conduct toll fraud, resulting in unexpected financial impact to affected customers.
CVE-1999-0293 1 Cisco 1 Ios 2024-02-07 7.5 HIGH N/A
AAA authentication on Cisco systems allows attackers to execute commands without authorization.
CVE-2023-20186 1 Cisco 2 Ios, Ios Xe 2024-01-25 N/A 9.1 CRITICAL
A vulnerability in the Authentication, Authorization, and Accounting (AAA) feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to bypass command authorization and copy files to or from the file system of an affected device using the Secure Copy Protocol (SCP). This vulnerability is due to incorrect processing of SCP commands in AAA command authorization checks. An attacker with valid credentials and level 15 privileges could exploit this vulnerability by using SCP to connect to an affected device from an external machine. A successful exploit could allow the attacker to obtain or change the configuration of the affected device and put files on or retrieve files from the affected device.
