DISPUTED PHP remote file inclusion vulnerability in includes/usercpregister.php in phpBB 2.0.19 allows remote attackers to execute arbitrary PHP code via a URL in the phpbbrootpath parameter. NOTE: this issue has been disputed by third-party researchers, stating that the file checks for a global constant and cannot be accessed directly.
phpBB 2.0.20 does not verify user-specified input variable types before being passed to type-dependent functions, which allows remote attackers to obtain sensitive information, as demonstrated by the (1) mode parameter to memberlist.php and the (2) highlight parameter to viewtopic.php that are used as an argument to the htmlspecialchars or urlencode functions, which displays the installation path in the resulting error message.
Certain forms in phpBB before 2.0.22 lack session checks, which has unknown impact and remote attack vectors.
Unspecified vulnerability in phpBB before 2.0.22 has unknown impact and remote attack vectors related to a "negative start parameter."
Unspecified vulnerability in phpBB before 2.0.22 has unknown impact and remote attack vectors related to "criteria for 'bad' redirection targets."
Cross-site request forgery (CSRF) vulnerability in phpBB 2.0.21 allows remote authenticated users to send unauthorized messages as an arbitrary user via unspecified vectors. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
Cross-site scripting (XSS) vulnerability in the private message box implementation (privmsg.php) in phpBB 2.0.x allows remote authenticated users to inject arbitrary web script or HTML via the "Message body" field in a message to a non-existent user.
DISPUTED PHP remote file inclusion vulnerability in groupcp.php in phpBB 2.0.10 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the phpbbrootpath parameter. NOTE: CVE and the vendor dispute this vulnerability because $phpbbrootpath is defined before use.
PHP remote file inclusion vulnerability in admin/admintopicactionlogging.php in Admin Topic Action Logging Mod 0.95 and earlier, as used in phpBB 2.0 up to 2.0.21, allows remote attackers to execute arbitrary PHP code via a URL in the phpbbrootpath parameter.
phpBB 2.0.21 does not properly handle pathnames ending in %00, which allows remote authenticated administrative users to upload arbitrary files, as demonstrated by a query to admin/adminboard.php with an avatarpath parameter ending in .php%00.
usercpavatar.php in PHPBB 2.0.20, when avatar uploading is enabled, allows remote attackers to use the server as a web proxy by submitting a URL to the avatarurl parameter, which is then used in an HTTP GET request.
DISPUTED PHP remote file inclusion vulnerability in template.php in phpBB 2 allows remote attackers to execute arbitrary PHP code via a URL in the page parameter. NOTE: followup posts have disputed this issue, stating that template.php does not appear in phpBB and does not use a $page variable. It is possible that this is a site-specific vulnerability, or an issue in a mod.
SQL injection vulnerability in charts.php in the Chart mod for phpBB allows remote attackers to execute arbitrary SQL commands via the id parameter.
Cross-site scripting (XSS) vulnerability in charts.php in the Chart mod for phpBB allows remote attackers to inject arbitrary web script or HTML via the id parameter. NOTE: this issue might be resultant from SQL injection.
PHP remote file inclusion vulnerability in /includes/kbconstants.php in Knowledge Base Mod for PHPbb 2.0.2 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the modulerootpath parameter.
Unspecified vulnerability in phpBB allows remote authenticated users with Administration Panel access to execute arbitrary PHP code via crafted Font Colour 3 ($theme[fontcolor3] variable) and/or signature values, possibly involving the highlight functionality. NOTE: the original report does not clarify whether this issue is static code injection, eval injection, or another type of vulnerability.
Direct static code injection vulnerability in includes/template.php in phpBB allows remote authenticated users with write access to execute arbitrary PHP code by modifying a template in a way that (1) bypasses a loose "." regular expression to match BEGIN and END statements in overallheader.tpl, or (2) is used in an eval statement by includes/bbcode.php for bbcode.tpl.
Cross-site scripting (XSS) vulnerability in profile.php in phpBB 2.0.19 allows remote attackers to inject arbitrary web script or HTML via the curpassword parameter. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
The genrandstring function in phpBB 2.0.19 uses insufficiently random data (small value space) to create the activation key ("validation ID") that is sent by e-mail when establishing a password, which makes it easier for remote attackers to obtain the key and modify passwords for existing accounts or create new accounts.
Cross-site request forgery (CSRF) vulnerability in phpBB 2.0.19, when Link to off-site Avatar or bbcode (IMG) are enabled, allows remote attackers to perform unauthorized actions as a logged in user via a link or IMG tag in a user profile, as demonstrated using links to (1) admin/adminusers.php and (2) modcp.php.
Cross-site scripting (XSS) vulnerability in adminsmilies.php in phpBB 2.0.19 allows remote attackers to inject arbitrary web script or HTML via Javascript events such as "onmouseover" in the (1) smileurl or (2) smileemotion parameters, which bypasses a check for "<" and ">" characters.
phpBB 2.0.19 and earlier allows remote attackers to cause a denial of service (application crash) by (1) registering many users through profile.php or (2) using search.php to search in a certain way that confuses the database.
Cross-site scripting (XSS) vulnerability in phpBB 2.0.19, when "Allowed HTML tags" is enabled, allows remote attackers to inject arbitrary web script or HTML via a permitted HTML tag with ' (single quote) characters and active attributes such as onmouseover, a variant of CVE-2005-4357.
SQL injection vulnerability in phpBB 2 before 2.0.18 allows remote attackers to execute arbitrary SQL commands via the topic type.
A "missing request validation" error in phpBB 2 before 2.0.18 allows remote attackers to edit private messages of other users, probably by modifying certain parameters or other inputs.
Cross-site scripting (XSS) vulnerability in phpBB 2.0.18, when "Allowed HTML tags" is enabled, allows remote attackers to inject arbitrary Javascript via a permitted HTML tag with " (quote) characters and active attributes such as onmouseover.
admin/admindisallow.php in phpBB 2.0.18 allows remote attackers to obtain the installation path via a direct request with a non-empty setmodules parameter, which causes an invalid appendsid function call that leaks the path in an error message.
phpBB 2.0.18 allows remote attackers to obtain sensitive information via a large SQL query, which generates an error message that reveals SQL syntax or the full installation path.
usercpregister.php in phpBB 2.0.17 allows remote attackers to modify regular expressions and execute PHP code via the signaturebbcodeuid parameter, as demonstrated by injecting an "e" modifier into a pregreplace statement.
phpBB 2.0.17 and earlier allows remote attackers to bypass protection mechanisms that deregister global variables by setting both a GET/POST/COOKIE (GPC) variable and a GLOBALS[] variable with the same name, which causes phpBB to unset the GLOBALS[] variable but not the GPC variable.
