CVE Vulnerability Advisory Database

[Affected Scope] Cisco network devices running Cisco IOS or IOS XE Software with the Autonomic Networking feature enabled (specifically Denali-16.2.1, Denali-16.3.1)

[Impact] An unauthenticated, adjacent attacker can cause affected autonomic nodes to reload, leading to a complete Denial of Service (DoS) condition

[Mitigation] Apply official Cisco software updates or disable the Autonomic Networking Infrastructure (ANI) feature if not required

[Affected Scope] Cisco IOS and IOS XE Software with SNMP enabled and affected MIBs/OIDs not explicitly excluded

[Impact] An authenticated, remote attacker can execute arbitrary code with full system control or cause a denial of service (system reload)

[Mitigation] Apply official Cisco software updates, or implement workarounds by restricting SNMP views to exclude vulnerable MIBs and enforcing ACLs

[Affected Scope] Cisco IOS and IOS XE Software with SNMP enabled and affected MIBs/OIDs not explicitly excluded

[Impact] Authenticated remote attackers can execute arbitrary code with full system privileges or trigger a device reload (DoS) via crafted SNMP packets

[Mitigation] Apply official Cisco software updates, restrict SNMP access using ACLs, enforce strong community strings/credentials, or disable vulnerable MIB views

[Affected Scope] Cisco IOS and IOS-XE devices with active SNMP services and exposed valid credentials (community strings or SNMPv3 users)

[Impact] An authenticated remote attacker can send crafted SNMP packets to trigger a buffer overflow, causing a system reload (DoS) or executing arbitrary code with full administrative privileges

[Mitigation] Apply official Cisco software updates, restrict SNMP access using strict Access Control Lists (ACLs), or disable SNMP services if not required

[Affected Scope] All Cisco devices running Cisco IOS or IOS XE software with SNMP enabled and affected MIBs/OIDs not explicitly excluded

[Impact] An authenticated, remote attacker can execute arbitrary code with full system privileges or trigger a device reload, causing a complete Denial of Service (DoS)

[Mitigation] Apply official software updates via Cisco IOS Software Checker, or implement workarounds including SNMP View restrictions and Access Control Lists (ACLs)

[Affected Scope] Cisco IOS and IOS-XE devices with active SNMP services and exposed community strings or user credentials.

[Impact] Authenticated remote attackers can trigger a buffer overflow via crafted SNMP packets, leading to system reload (DoS) or full remote code execution (RCE) with administrative privileges.

[Mitigation] Apply official Cisco software updates, restrict SNMP access using strict Access Control Lists (ACLs), or disable SNMP services if not required.

[Affected Scope] Cisco IOS and IOS XE Software with SNMP enabled and affected MIBs/OIDs not explicitly excluded

[Impact] Authenticated remote attackers can execute arbitrary code with full system control or trigger a device reload by sending crafted SNMP packets

[Mitigation] Apply official software updates via Cisco IOS Software Checker, or implement SNMPv3 hardening and MIB filtering workarounds

[Affected Scope] Cisco IOS and IOS-XE network devices with active SNMP services and exposed valid credentials (community strings or SNMPv3 user credentials).

[Impact] An authenticated, remote attacker can send crafted SNMP packets to trigger a buffer overflow, leading to a system reload or arbitrary remote code execution (RCE) with full administrative control.

[Mitigation] Apply official Cisco software patches immediately, or restrict SNMP access using Infrastructure ACLs and enforce complex community strings as a temporary workaround.

[Affected Scope] All Cisco devices running Cisco IOS and IOS XE Software with SNMP enabled and affected MIBs/OIDs not explicitly excluded

[Impact] Authenticated remote attackers can execute arbitrary code with full system privileges or trigger a device reload, leading to complete infrastructure compromise or denial of service

[Mitigation] Apply fixed software versions via Cisco IOS Software Checker, or implement workarounds including SNMP community ACLs, MIB view restrictions, or disabling SNMP

[Affected Scope] Cisco IOS and IOS XE-based Catalyst switches and embedded service modules configured to accept Telnet connections and utilizing CMP

[Impact] Unauthenticated, remote attackers can execute arbitrary code with elevated privileges or cause a device reload by sending malformed CMP-specific Telnet options

[Mitigation] Apply official Cisco software updates immediately, or disable Telnet services and restrict VTY access using infrastructure ACLs

[Affected Scope] Cisco IOS 12.2 through 12.4 and 15.0 through 15.6, IOS XE through 3.18S, IOS XR 4.3.x and 5.0.x through 5.2.x, and PIX before 7.0

[Impact] Unauthenticated remote attackers can retrieve sensitive information from device memory (including private keys and configuration data) by sending crafted IKEv1 negotiation requests

[Mitigation] Upgrade affected device firmware to the latest patched releases, or restrict access to UDP ports 500 and 4500 using infrastructure ACLs to trusted peers only

[Affected Scope] Apple iPhone, iPad, and iPod touch devices running iOS versions prior to 9.3.5, and applications utilizing the WebKit rendering engine

[Impact] Remote attackers can execute arbitrary code or cause a denial of service (memory corruption) by enticing a user to visit a specially crafted website

[Mitigation] Immediately update the operating system of affected devices to iOS 9.3.5 or later

[Affected Scope] All Apple iOS devices running versions prior to iOS 9.3.5

[Impact] Attackers can execute arbitrary code with kernel privileges or cause a denial of service (memory corruption) via a crafted application

[Mitigation] Immediately update affected devices to iOS 9.3.5 or the latest available OS version

[Affected Scope] All Apple iOS devices running versions prior to iOS 9.3.5

[Impact] Local attackers or malicious apps can read sensitive kernel memory, allowing them to bypass Kernel Address Space Layout Randomization (KASLR) and facilitate full system compromise

[Mitigation] Immediately update all affected iOS devices to iOS 9.3.5 or later

[Affected Scope] Apple iOS versions prior to 8 and Apple TV versions prior to 7.

[Impact] A local attacker can execute arbitrary code with kernel privileges (privileged context) via a crafted application, leading to complete system compromise.

[Mitigation] Immediately update the affected devices to iOS 8, Apple TV 7, or later versions.

[Affected Scope] Cisco 871 Integrated Services Routers (ISR) running Cisco IOS 12.4 with the HTTP Administration component enabled.

[Impact] Remote attackers can execute arbitrary commands with privilege level 15 by tricking an authenticated administrator into visiting a malicious link, leading to complete device compromise.

[Mitigation] Disable the HTTP/HTTPS server on the router, restrict access using IP-based Access Control Lists (ACLs), or upgrade to a patched Cisco IOS release.

[Affected Scope] Cisco IOS 12.2(15) and earlier versions

[Impact] Remote attackers can cause a denial of service (refused VTY connections) by exhausting virtual terminal resources using crafted TCP connection requests

[Mitigation] Upgrade to a patched Cisco IOS release, disable Telnet in favor of SSH, and restrict VTY access using Access Control Lists (ACLs)
