Related Weaknesses

CWE-ID	Weakness Name	Source
CWE-20	Improper Input Validation The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
CWE-119	Improper Restriction of Operations within the Bounds of a Memory Buffer The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

MSN messenger 7.x (8.0?) VIDEO Remote Heap Overflow Exploit thanks ole andre again, His ospy is perfect. 1.compile the dll. 2.inject the dll to msn messenger 7.0.777.0 's process. 3. choose "send my webcam" to a contact id who is online using 7.x (8.0?). 4.when the otherside accept the invatation , the otherside's msn will be at least crashed, if you using aChinese version windows 2000 sp4 , maybe a reverse shell , if other verison windows 2000, you need adjust the jmpa address in the dll's sourcecode. https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/30537.rar (08292007-exp_msn.rar) # milw0rm.com [2007-08-29]

source: https://www.securityfocus.com/bid/25461/info Microsoft MSN Messenger is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the application. Failed exploit attempts will likely result in denial-of-service conditions. https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/30537.rar
