Exemples observés

Description |
| Classic "Smurf" attack, using spoofed ICMP packets to broadcast addresses. |
| Parsing library allows XML bomb |
| Tool creates directories before authenticating user. |
| Python has "quadratic complexity" issue when converting string to int with many digits in unexpected bases |
| server allows ReDOS with crafted User-Agent strings, due to overlapping capture groups that cause excessive backtracking. |
| composite: NTP feature generates large responses (high amplification factor) with spoofed UDP source addresses. |
| Diffie-Hellman (DHE) Key Agreement Protocol allows attackers to send arbitrary numbers that are not public keys, which causes the server to perform expensive, unnecessary computation of modular exponentiation. |
| The Diffie-Hellman Key Agreement Protocol allows use of long exponents, which are more computationally expensive than using certain "short exponents" with particular properties. |
Mesures d’atténuation potentielles
Phases : Architecture and Design
An application must make resources available to a client commensurate with the client's access level.
Phases : Architecture and Design
An application must, at all times, keep track of allocated resources and meter their usage appropriately.
Phases : System Configuration
Consider disabling resource-intensive algorithms on the server side, such as Diffie-Hellman key exchange.
