The SCP server in Cisco IOS 12.2 through 12.4, when Role-Based CLI Access is enabled, does not enforce the CLI view configuration for file transfers, which allows remote authenticated users with an attached CLI view to (1) read or (2) overwrite arbitrary files via an SCP command.

The (1) Cisco Unified Communications Manager Express; (2) SIP Gateway Signaling Support Over Transport Layer Security (TLS) Transport; (3) Secure Signaling and Media Encryption; (4) Blocks Extensible Exchange Protocol (BEEP); (5) Network Admission Control HTTP Authentication Proxy; (6) Per-user URL Redirect for EAPoUDP, Dot1x, and MAC Authentication Bypass; (7) Distributed Director with HTTP Redirects; and (8) TCP DNS features in Cisco IOS 12.0 through 12.4 do not properly handle IP sockets, which allows remote attackers to cause a denial of service (outage or resource consumption) via a series of crafted TCP packets.

The (1) Airline Product Set (aka ALPS), (2) Serial Tunnel Code (aka STUN), (3) Block Serial Tunnel Code (aka BSTUN), (4) Native Client Interface Architecture (NCIA) support, (5) Data-link switching (aka DLSw), (6) Remote Source-Route Bridging (RSRB), (7) Point to Point Tunneling Protocol (PPTP), (8) X.25 for Record Boundary Preservation (RBP), (9) X.25 over TCP (XOT), and (10) X.25 Routing features in Cisco IOS 12.2 and 12.4 allows remote attackers to cause a denial of service (device reload) via a series of crafted TCP packets.

Unspecified vulnerability in Cisco IOS 12.0 through 12.4, when configured with (1) IP Service Level Agreements (SLAs) Responder, (2) Session Initiation Protocol (SIP), (3) H.323 Annex E Call Signaling Transport, or (4) Media Gateway Control Protocol (MGCP) allows remote attackers to cause a denial of service (blocked input queue on the inbound interface) via a crafted UDP packet.

Multiple cross-site scripting (XSS) vulnerabilities in the HTTP server in Cisco IOS 11.0 through 12.4 allow remote attackers to inject arbitrary web script or HTML via (1) the query string to the ping program or (2) unspecified other aspects of the URI.

The Temporal Key Integrity Protocol (TKIP) implementation in unspecified Cisco products and other vendors' products, as used in WPA and WPA2 on Wi-Fi networks, has insufficient countermeasures against certain crafted and replayed packets, which makes it easier for remote attackers to decrypt packets from an access point (AP) to a client and spoof packets from an AP to a client, and conduct ARP poisoning attacks or other attacks, as demonstrated by tkiptun-ng.

Unspecified vulnerability in the VLAN Trunking Protocol (VTP) implementation on Cisco IOS and CatOS, when the VTP operating mode is not transparent, allows remote attackers to cause a denial of service (device reload or hang) via a crafted VTP packet sent to a switch interface configured as a trunk port.

The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.

Cisco IOS 12.0 through 12.4 on Gigabit Switch Router (GSR) devices (aka 12000 Series routers) allows remote attackers to cause a denial of service (device crash) via a malformed Protocol Independent Multicast (PIM) packet.

Unspecified vulnerability in Cisco IOS 12.0 through 12.4 allows remote attackers to cause a denial of service (device reload) via a crafted Protocol Independent Multicast (PIM) packet.

Cross-site scripting (XSS) vulnerability in Cisco IOS allows remote attackers to inject arbitrary web script or HTML, and execute IOS commands, via unspecified vectors, aka PSIRT-2022590358. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Multiple stack-based buffer overflows in Command EXEC in Cisco IOS allow local users to gain privileges via unspecified vectors, aka (1) PSIRT-0474975756 and (2) PSIRT-0388256465. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Unspecified vulnerability in Command EXEC in Cisco IOS allows local users to bypass command restrictions and obtain sensitive information via an unspecified "variation of an IOS command" involving "two different methods", aka CSCsk16129. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Unspecified vulnerability in Cisco IOS allows remote attackers to obtain the IOS version via unspecified vectors involving a "common network service", aka PSIRT-1255024833. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Off-by-one error in Cisco IOS allows remote attackers to execute arbitrary code via unspecified vectors that trigger a heap-based buffer overflow. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Integer overflow in Cisco IOS allows remote attackers to execute arbitrary code via unspecified vectors. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Stack-based buffer overflow in the Line Printer Daemon (LPD) in Cisco IOS before 12.2(18)SXF11, 12.4(16a), and 12.4(2)T6 allow remote attackers to execute arbitrary code by setting a long hostname on the target system, then causing an error message to be printed, as demonstrated by a telnet session to the LPD from a source port other than 515.
