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 | The version of Symantec Encryption Management Server running on the remote host is 3.3.2 prior to version 3.3.2 MP12. It is, therefore, affected by multiple vulnerabilities : - An unspecified flaw in the LDAP service allows a remote attacker, via a crafted LDAP request, to gather sensitive information about valid administrator accounts on the server. (CVE-2015-8148) - A denial of service exists in the LDAP service due to a failure to properly validate user-supplied input. An unauthenticated, remote attacker can exploit this, via crafted request packets, to cause corrupted memory block headers, leading to a SIGSEGV fault and resulting in a service halt. (CVE-2015-8149) - An unspecified flaw exists that is related to scheduling commands to run via existing batch files, which normally run with root privileges. A local attacker can exploit this to gain elevated privileges on the server. (CVE-2015-8150) - A command injection vulnerability exists in the web user interface due to a failure to properly sanitize certain user-supplied input fields. An authenticated, remote attacker can exploit this to run arbitrary commands with elevated privileges on the underlying operating system. (CVE-2015-8151) |
