Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| description | According to its banner, the remote host is running version 14.x of RealNetworks Helix Server / Helix Mobile Server. Such versions are potentially affected by multiple vulnerabilities : - Administrative and user credentials are insecurely stored in a flat file database. This file may be accessed by local users to disclose passwords stored in plaintext. (CVE-2012-1923) - A buffer overflow exists in the code that parses authentication credentials. It may be possible for a remote attacker to exploit this issue and execute arbitrary code. (CVE-2012-0942) - Multiple unspecified cross-site scripting vulnerabilities. (CVE-2012-1984) - A specially crafted malformed URL can cause the server process to crash if opened by an administrator. (CVE-2012-1985) - Establishing and immediately closing a TCP connection on port 705 can cause the SNMP Master Agent to crash. (CVE-2012-2267) - A specially crafted Open-PDU request sent to the SNMP Master Agent can cause it to crash due to an unhandled exception. (CVE-2012-2268) |
