"The version of Adobe Connect installed on the remote host is prior to 12.9. It is, therefore, affected by multiple
vulnerabilities as referenced in the apsb25-36 advisory.

  - Adobe Connect versions 12.8 and earlier are affected by a reflected Cross-Site Scripting (XSS)
    vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields.
    Malicious JavaScript may be executed in a victim's browser when they browse to the page containing the
    vulnerable field. A successful attacker can abuse this to achieve session takeover, increasing the
    confidentiality and integrity impact as high. (CVE-2025-43567)

  - Adobe Connect versions 12.8 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability
    that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious
    JavaScript may be executed in a victim's browser when they browse to the page containing the vulnerable
    field. (CVE-2025-30314, CVE-2025-30315)

  - Adobe Connect versions 12.8 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability
    that could be abused by a low privileged attacker to inject malicious scripts into vulnerable form fields.
    Malicious JavaScript may be executed in a victim's browser when they browse to the page containing the
    vulnerable field. (CVE-2025-30316)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
