Copyparty
Monthly
If an attacker has been given both read- and write-permissions to the server, they can upload a malicious file with the filename `.prologue.html` and then craft a link to potentially execute arbitrary JavaScript in the victim's context. Note that it is intended behavior that the JavaScript would execute if the target clicks a link to the HTML file itself; "https://example.com/foo/.prologue.html". The vulnerability is that "https://example.com/foo/?b" would also evaluate the file, making the behavior unexpected. There are existing preventative measures (strict SameSite cookies) which makes it harder to leverage this vulnerability in an attack; in order to gain control of the target's authenticated session, the link must be clicked from a page served by the server itself -- most likely by editing an existing resource, which would require additional access permissions. Finally, for this attack to be successful, the attacker's target must click the specific crafted link given by the attacker. This vulnerability is not activated by normally browsing the web-UI on the server. ## Impact If successful, the malicious JavaScript could move or delete existing files on the server, or upload new files, using the account of the person who opens the link.
A security vulnerability in Copyparty (CVSS 6.5). Remediation should follow standard vulnerability management procedures.
Copyparty versions before 1.20.11 fail to apply the nohtml security restriction to SVG files, allowing authenticated users with write permissions to upload SVG images containing malicious JavaScript that executes when opened by other users. This cross-site scripting vulnerability bypasses the intended protection against JavaScript execution in user-uploaded content. The vulnerability has been patched in version 1.20.11.
Reflected XSS in Copyparty before version 1.20.9 allows unauthenticated attackers to inject malicious scripts through the setck URL parameter, potentially enabling session hijacking or credential theft from affected users. The vulnerability requires user interaction to click a crafted link but can be exploited remotely without authentication. A patch is available in version 1.20.9 and later.
Copyparty is a portable file server. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, low attack complexity.
Cross Site Scripting vulnerability in copyparty before 1.9.2 allows a local attacker to execute arbitrary code via a crafted payload to the WEEKEND-PLANS function. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Copyparty is a portable file server. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
copyparty, a portable file server, has a DOM-based cross-site scripting vulnerability in versions prior to 1.16.15. Rated low severity (CVSS 3.6), this vulnerability is no authentication required. Public exploit code available.
copyparty is file server software. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
