    CVE-2020-11939 (GCVE-0-2020-11939)

    Vulnerability from nvd – Published: 2020-04-23 14:18 – Updated: 2024-08-04 11:42
    VLAI
    Summary
    In nDPI through 3.2 Stable, the SSH protocol dissector has multiple KEXINIT integer overflows that result in a controlled remote heap overflow in concat_hash_string in ssh.c. Due to the granular nature of the overflow primitive and the ability to control both the contents and layout of the nDPI library's heap memory through remote input, this vulnerability may be abused to achieve full Remote Code Execution against any network inspection stack that is linked against nDPI and uses it to perform network traffic analysis.
    Severity

    CVE-2018-12520 (GCVE-0-2018-12520)

    Vulnerability from nvd – Published: 2018-07-05 20:00 – Updated: 2024-08-05 08:38
    VLAI
    Summary
    An issue was discovered in ntopng 3.4 before 3.4.180617. The PRNG involved in the generation of session IDs is not seeded at program startup. This results in deterministic session IDs being allocated for active user sessions. An attacker with foreknowledge of the operating system and standard library in use by the host running the service and the username of the user whose session they're targeting can abuse the deterministic random number generation in order to hijack the user's session, thus escalating their access.
    Severity

    CVE-2020-11939 (GCVE-0-2020-11939)

    Vulnerability from cvelistv5 – Published: 2020-04-23 14:18 – Updated: 2024-08-04 11:42
    VLAI
    Summary
    In nDPI through 3.2 Stable, the SSH protocol dissector has multiple KEXINIT integer overflows that result in a controlled remote heap overflow in concat_hash_string in ssh.c. Due to the granular nature of the overflow primitive and the ability to control both the contents and layout of the nDPI library's heap memory through remote input, this vulnerability may be abused to achieve full Remote Code Execution against any network inspection stack that is linked against nDPI and uses it to perform network traffic analysis.

    CVE-2018-12520 (GCVE-0-2018-12520)

    Vulnerability from cvelistv5 – Published: 2018-07-05 20:00 – Updated: 2024-08-05 08:38
    VLAI
    Summary
    An issue was discovered in ntopng 3.4 before 3.4.180617. The PRNG involved in the generation of session IDs is not seeded at program startup. This results in deterministic session IDs being allocated for active user sessions. An attacker with foreknowledge of the operating system and standard library in use by the host running the service and the username of the user whose session they're targeting can abuse the deterministic random number generation in order to hijack the user's session, thus escalating their access.
    Severity
