The version of lighttpd installed on the remote host is prior to 1.4.53-1.37. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1705 advisory.

  - In lighttpd 1.4.65, mod_wstunnel does not initialize a handler function pointer if an invalid HTTP request     (websocket handshake) is received. It leads to null pointer dereference which crashes the server. It could     be used by an external attacker to cause denial of service condition. (CVE-2022-37797)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This Solaris system is missing necessary patches to address critical security updates :

  - Vulnerability in the Oracle Text (LibExpat) component of     Oracle Database Server. Supported versions that are     affected are 19.3-19.19 and 21.3-21.10. Easily     exploitable vulnerability allows low privileged attacker     having Create Session, Create Index privilege with     network access via Oracle Net to compromise Oracle Text     (LibExpat). Successful attacks of this vulnerability can     result in unauthorized ability to cause a hang or     frequently repeatable crash (complete DOS) of Oracle     Text (LibExpat). CVSS 3.1 Base Score 6.5 (Availability     impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
    (CVE-2022-43680)

  - Vulnerability in the PeopleSoft Enterprise PeopleTools     product of Oracle PeopleSoft (component: Porting     (Python)). Supported versions that are affected are 8.59     and 8.60. Easily exploitable vulnerability allows     unauthenticated attacker with network access via HTTP to     compromise PeopleSoft Enterprise PeopleTools. Successful     attacks of this vulnerability can result in unauthorized     ability to cause a hang or frequently repeatable crash     (complete DOS) of PeopleSoft Enterprise PeopleTools.
    CVSS 3.1 Base Score 7.5 (Availability impacts). CVSS     Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
    (CVE-2022-45061)

  - Vulnerability in the Oracle Solaris product of Oracle     Systems (component: NSSwitch). Supported versions that     are affected are 10 and 11. Difficult to exploit     vulnerability allows high privileged attacker with     network access via multiple protocols to compromise     Oracle Solaris. Successful attacks require human     interaction from a person other than the attacker and     while the vulnerability is in Oracle Solaris, attacks     may significantly impact additional products (scope     change). Successful attacks of this vulnerability can     result in unauthorized update, insert or delete access     to some of Oracle Solaris accessible data and     unauthorized ability to cause a partial denial of     service (partial DOS) of Oracle Solaris. CVSS 3.1 Base     Score 4.0 (Integrity and Availability impacts). CVSS     Vector: (CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:L/A:L).
    (CVE-2023-21900)

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5243 advisory.

  - A resource leak in gw_backend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service     (connection-slot exhaustion) after a large amount of anomalous TCP behavior by clients. It is related to     RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of mod_fastcgi is, for example, affected.
    This is fixed in 1.4.67. (CVE-2022-41556)
