OwnCloud 8.1.8 contains a username enumeration vulnerability that allows remote attackers to discover user accounts by manipulating the share.php endpoint. Attackers can send crafted GET requests to /index.php/core/ajax/share.php with a wildcard search parameter to retrieve comprehensive user information.
The Docker image of ownCloud Server through 10.11 contains a misconfiguration that renders the trusteddomains config useless. This could be abused to spoof the URL in password-reset e-mail messages.
Inadequate escaping lead to XSS vulnerability in the search module in ownCloud Server before 8.2.12, 9.0.x before 9.0.10, 9.1.x before 9.1.6, and 10.0.x before 10.0.2. To be exploitable a user has to write or paste malicious content into the search dialogue.
A logical error in ownCloud Server before 10.0.2 caused disclosure of valid share tokens for public calendars. Thus granting an attacker potentially access to publicly shared calendars without knowing the share token.
An attacker is logged in as a normal user and can somehow make admin to delete shared folders in ownCloud Server before 10.0.2.
The autocomplete feature in the E-Mail share dialog in ownCloud Server before 8.1.11, 8.2.x before 8.2.9, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 allows remote authenticated users to obtain sensitive information via unspecified vectors.
The password reset functionality in ownCloud Server before 8.1.11, 8.2.x before 8.2.9, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 sends different error messages depending on whether the username is valid, which allows remote attackers to enumerate user names via a large number of password reset attempts.
ownCloud Server before 8.1.11, 8.2.x before 8.2.9, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 allows remote authenticated users to cause a denial of service (server hang and logfile flooding) via a one bit BMP file.
ownCloud server before 8.2.6 and 9.x before 9.0.3, when the gallery app is enabled, allows remote attackers to download arbitrary images via a direct request.
ownCloud Server before 4.5.7 does not properly check ownership of calendars, which allows remote authenticated users to read arbitrary calendars via the calid parameter to /apps/calendar/export.php. NOTE: this issue has been reported as a cross-site request forgery (CSRF) vulnerability, but due to lack of details, it is uncertain what the root cause is.
ownCloud Server before 5.0.15 and 6.0.x before 6.0.2 allows remote attackers to conduct an LDAP injection attack via unspecified vectors, as demonstrated using a "login query."
Unspecified vulnerability in ownCloud Server before 4.0.12 allows remote attackers to obtain sensitive information via unspecified vectors related to "inclusion of the Amazon SDK testing suite." NOTE: due to lack of details, it is not clear whether the issue exists in ownCloud itself, or in Amazon SDK.
PHPExcel before 1.8.0, as used in ownCloud Server before 5.0.15 and 6.0.x before 6.0.2, does not disable external entity loading in libxml, which allows remote attackers to read arbitrary files, cause a denial of service, or possibly have other impact via an XML External Entity (XXE) attack.
getID3() before 1.9.8, as used in ownCloud Server before 5.0.15 and 6.0.x before 6.0.2, allows remote attackers to read arbitrary files, cause a denial of service, or possibly have other impact via an XML External Entity (XXE) attack.
The installation routine in ownCloud Server before 4.0.14, 4.5.x before 4.5.9, and 5.0.x before 5.0.4 uses the time function to seed the generation of the PostgreSQL database user password, which makes it easier for remote attackers to guess the password via a brute force attack.
Multiple cross-site request forgery (CSRF) vulnerabilities in ownCloud Server before 6.0.3 allow remote attackers to hijack the authentication of users for requests that (1) conduct cross-site scripting (XSS) attacks, (2) modify files, or (3) rename files via unspecified vectors.
ownCloud Server before 6.0.1 does not properly check permissions, which allows remote authenticated users to access arbitrary preview pictures via unspecified vectors.
The document application in ownCloud Server before 6.0.3 uses sequential values for the fileid, which allows remote authenticated users to enumerate shared files via unspecified vectors.
Cross-site scripting (XSS) vulnerability in the Documents component in ownCloud Server 6.0.x before 6.0.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, possibly related to the printunescaped function.
settings/personal.php in ownCloud 4.5.x before 4.5.6 allows remote authenticated users to execute arbitrary PHP code via crafted mount point settings.
Multiple cross-site scripting (XSS) vulnerabilities in ownCloud Server before 4.0.8 allow remote attackers to inject arbitrary web script or HTML via the (1) readyCallback parameter to apps/filesodfviewer/src/webodf/webodf/flashput/PUT.swf, the (2) root parameter to apps/gallery/templates/index.php, or a (3) malformed query to lib/db.php.
ownCloud Server before 5.0.16 and 6.0.x before 6.0.3 does not check permissions to the filesexternal application, which allows remote authenticated users to add external storage via unspecified vectors.
Multiple cross-site scripting (XSS) vulnerabilities in the (1) Gallery and (2) core components in ownCloud Server before 5.016 and 6.0.x before 6.0.3 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors, possibly related to the printunescaped function.
PHPDocX, as used in ownCloud Server before 5.0.15 and 6.0.x before 6.0.2, allows remote attackers to read arbitrary files, cause a denial of service, or possibly have other impact via an XML External Entity (XXE) attack.
ownCloud Server before 5.0.16 and 6.0.x before 6.0.3 does not properly check permissions, which allows remote authenticated users to read the names of files of other users by leveraging access to multiple accounts.
CRLF injection vulnerability in ownCloud Server before 4.0.8 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via the url path parameter.
lib/base.php in ownCloud before 4.0.8 does not properly validate the userid session variable, which allows remote authenticated users to read arbitrary files via vectors related to WebDAV.
ownCloud Server before 6.0.3 does not properly check permissions, which allows remote authenticated users to (1) access the contacts of other users via the address book or (2) rename files via unspecified vectors.
ownCloud before 5.0.15 and 6.x before 6.0.2, when the fileexternal app is enabled, allows remote authenticated users to mount the local filesystem in the user's ownCloud via the mount configuration.
Multiple cross-site scripting (XSS) vulnerabilities in ownCloud before 6.0.2 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.
