CVE Descriptions
Buffer overflow in Serv-U FTP server before 5.0.0.6 allows remote attackers to cause a denial of service (crash) via a long -l parameter, which triggers an out-of-bounds read.
CVE Informations
Related Weaknesses
| Weakness Name | Source | |
|---|---|---|
| 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.

Reportedly Serv-U is affected by a remote buffer overflow vulnerability in the list parameter. This issue is due to a failure of the application to properly validate buffer boundaries during processing of user input.
Successful exploitation would immediately produce a denial of service condition in the affected process. This issue may also be leveraged to execute code on the affected system with the privileges of the user that invoked the vulnerable application, although this has not been confirmed.
