CVE-2008-3800 1 Cisco 3 Ios, Unified Callmanager, Unified Communications Manager 2022-06-02 7.1 HIGH N/A
Unspecified vulnerability in the Session Initiation Protocol (SIP) implementation in Cisco IOS 12.2 through 12.4 and Unified Communications Manager 4.1 through 6.1, when VoIP is configured, allows remote attackers to cause a denial of service (device or process reload) via unspecified valid SIP messages, aka Cisco Bug ID CSCsu38644, a different vulnerability than CVE-2008-3801 and CVE-2008-3802.
CVE-2008-3799 1 Cisco 1 Ios 2022-06-02 7.8 HIGH N/A
Memory leak in the Session Initiation Protocol (SIP) implementation in Cisco IOS 12.2 through 12.4, when VoIP is configured, allows remote attackers to cause a denial of service (memory consumption and voice-service outage) via unspecified valid SIP messages.
CVE-2008-3798 1 Cisco 1 Ios 2022-06-02 7.8 HIGH N/A
Cisco IOS 12.4 allows remote attackers to cause a denial of service (device crash) via a normal, properly formed SSL packet that occurs during termination of an SSL session.
CVE-2007-0918 1 Cisco 1 Ios 2022-06-02 7.1 HIGH N/A
The ATOMIC.TCP signature engine in the Intrusion Prevention System (IPS) feature for Cisco IOS 12.4XA, 12.3YA, 12.3T, and other trains allows remote attackers to cause a denial of service (IPS crash and traffic loss) via unspecified manipulations that are not properly handled by the regular expression feature, as demonstrated using the 3123.0 (Netbus Pro Traffic) signature.

CVE-2008-4128 1 Cisco 2 Integrated Services Router 871, Ios 2022-05-23 9.3 HIGH N/A
Multiple cross-site request forgery (CSRF) vulnerabilities in the HTTP Administration component in Cisco IOS 12.4 on the 871 Integrated Services Router allow remote attackers to execute arbitrary commands via (1) a certain "show privilege" command to the /level/15/exec/- URI, and (2) a certain "alias exec" command to the /level/15/exec/-/configure/http URI. NOTE: some of these details are obtained from third party information.
CVE-2022-20725 1 Cisco 67 800m Integrated Services Router, 807 Industrial Integrated Services Router, 812 3g Integrated Services Router and 64 more 2022-05-16 3.5 LOW 4.8 MEDIUM
Multiple vulnerabilities in the Cisco IOx application hosting environment on multiple Cisco platforms could allow an attacker to inject arbitrary commands into the underlying host operating system, execute arbitrary code on the underlying host operating system, install applications without being authenticated, or conduct a cross-site scripting (XSS) attack against a user of the affected software. For more information about these vulnerabilities, see the Details section of this advisory.
CVE-2021-1385 1 Cisco 2 Ios, Ios Xe 2022-05-12 6.0 MEDIUM 6.5 MEDIUM
A vulnerability in the Cisco IOx application hosting environment of multiple Cisco platforms could allow an authenticated, remote attacker to conduct directory traversal attacks and read and write files on the underlying operating system or host system. This vulnerability occurs because the device does not properly validate URIs in IOx API requests. An attacker could exploit this vulnerability by sending a crafted API request that contains directory traversal character sequences to an affected device. A successful exploit could allow the attacker to read or write arbitrary files on the underlying operating system.
CVE-2022-20697 1 Cisco 2 Ios, Ios Xe 2022-04-26 6.8 MEDIUM 8.6 HIGH
A vulnerability in the web services interface of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper resource management in the HTTP server code. An attacker could exploit this vulnerability by sending a large number of HTTP requests to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.
CVE-2022-20761 1 Cisco 1 Ios 2022-04-25 6.1 MEDIUM 6.5 MEDIUM
A vulnerability in the integrated wireless access point (AP) packet processing of the Cisco 1000 Series Connected Grid Router (CGR1K) could allow an unauthenticated, adjacent attacker to cause a denial of service condition on an affected device. This vulnerability is due to insufficient input validation of received traffic. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to cause the integrated AP to stop processing traffic, resulting in a DoS condition. It may be necessary to manually reload the CGR1K to restore AP operation.
