|---|---|---|---|
| 2003-03-31 | CVE-2002-1558 | Unspecified vulnerability in Cisco Optical Networking Systems Software Cisco ONS15454 and ONS15327 running ONS before 3.4 have an account for the VxWorks Operating System in the TCC, TCC+ and XTC that cannot be changed or disabled, which allows remote attackers to gain privileges by connecting to the account via Telnet. | 10.0 |
| 2002-12-23 | CVE-2002-1360 | Improper Input Validation vulnerability in multiple products Multiple SSH2 servers and clients do not properly handle strings with null characters in them when the string length is specified by a length field, which could allow remote attackers to cause a denial of service or possibly execute arbitrary code due to interactions with the use of null-terminated strings as implemented using languages such as C, as demonstrated by the SSHredder SSH protocol test suite. network low complexity cisco fissh intersoft netcomposite pragma-systems putty winscp CWE-20 critical | 10.0 |
| 2002-12-23 | CVE-2002-1359 | Improper Input Validation vulnerability in multiple products Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite. network low complexity cisco fissh intersoft netcomposite pragma-systems putty winscp CWE-20 critical | 10.0 |
| 2002-12-23 | CVE-2002-1358 | Improper Input Validation vulnerability in multiple products Multiple SSH2 servers and clients do not properly handle lists with empty elements or strings, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite. network low complexity cisco fissh intersoft netcomposite pragma-systems putty winscp CWE-20 critical | 10.0 |
| 2002-12-23 | CVE-2002-1357 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite. network low complexity cisco fissh intersoft netcomposite pragma-systems putty winscp CWE-119 critical | 10.0 |
| 2000-12-19 | CVE-2000-0945 | Unspecified vulnerability in Cisco Catalyst 3500 XL The web configuration interface for Catalyst 3500 XL switches allows remote attackers to execute arbitrary commands without authentication when the enable password is not set, via a URL containing the /exec/ directory. | 10.0 |
