Cross-site scripting (XSS) vulnerability in the process function in SSViewer.php in SilverStripe before 2.3.13 and 2.4.x before 2.4.6 allows remote attackers to inject arbitrary web script or HTML via the QUERY_STRING to template placeholders, as demonstrated by a request to (1) admin/reports/, (2) admin/comments/, (3) admin/, (4) admin/show/, (5) admin/assets/, and (6) admin/security/.

SilverStripe 2.3.x before 2.3.12 and 2.4.x before 2.4.6 allows remote authenticated users with the EDIT_PERMISSIONS permission to gain administrator privileges via a TreeMultiselectField that includes admin groups when adding a user to the selected groups.

SilverStripe 2.3.x before 2.3.10 and 2.4.x before 2.4.4 stores sensitive information under the web root with insufficient access control, which allows remote attackers to obtain version information via a direct request to (1) apphire/silverstripe_version or (2) cms/silverstripe_version.

code/sitefeatures/PageCommentInterface.php in SilverStripe 2.4.x before 2.4.6 might allow remote attackers to execute arbitrary code via a crafted cookie in a user comment submission, which is not properly handled when it is deserialized.

core/model/MySQLDatabase.php in SilverStripe 2.4.x before 2.4.4, when the site is running in "live mode," allows remote attackers to obtain the SQL queries for a page via the showqueries and ajax parameters.

Cross-site scripting (XSS) vulnerability in the httpError method in sapphire/core/control/RequestHandler.php in SilverStripe 2.3.x before 2.3.10 and 2.4.x before 2.4.4, when custom error handling is not used, allows remote attackers to inject arbitrary web script or HTML via "missing URL actions."

SQL injection vulnerability in the addslashes method in SilverStripe 2.3.x before 2.3.12 and 2.4.x before 2.4.6, when connected to a MySQL database using far east character encodings, allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

SilverStripe 2.3.x before 2.3.10 and 2.4.x before 2.4.4 uses weak entropy when generating tokens for (1) the CSRF protection mechanism, (2) autologin, (3) "forgot password" functionality, and (4) password salts, which makes it easier for remote attackers to bypass intended access restrictions via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in SilverStripe 2.3.x before 2.3.13 and 2.4.x before 2.4.7 allow remote attackers to inject arbitrary web script or HTML via (1) a crafted string to the AbsoluteLinks, (2) BigSummary, (3) ContextSummary, (4) EscapeXML, (5) FirstParagraph, (6) FirstSentence, (7) Initial, (8) LimitCharacters, (9) LimitSentences, (10) LimitWordCount, (11) LimitWordCountXML, (12) Lower, (13) LowerCase, (14) NoHTML, (15) Summary, (16) Upper, (17) UpperCase, or (18) URL method in a template, different vectors than CVE-2012-0976.

SQL injection vulnerability in the augmentSQL method in core/model/Translatable.php in SilverStripe 2.3.x before 2.3.10 and 2.4.x before 2.4.4, when the Translatable extension is enabled, allows remote attackers to execute arbitrary SQL commands via the locale parameter.
