According to MITRE, the most dangerous type of software bug is the out-of-bounds write, which has accounted for 70 active attacks on vulnerabilities in the US government’s list. Out-of-bounds write occurs when software alters memory it’s not supposed to, potentially allowing attackers to take control of the system. Cross-site scripting and SQL injection flaws are also identified as common and dangerous bugs. The annual CWE Top 25 list, compiled by MITRE, analyzes vulnerability data and highlights the need for software improvement. The list remains consistent year after year, indicating slow progress in addressing these issues. MITRE plans to publish reports to assist organizations in effectively addressing these vulnerabilities.
