| CVE | Vendors | Products | Updated | CVSS v3.1 | 
        | 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. | 
    
    
    
        | PHP remote file inclusion vulnerability in includes/usercp_register.php in phpBB 2.0.19 allows remote attackers to execute arbitrary PHP code via a URL in the phpbb_root_path 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 | 
    
    
    
        | PHP remote file inclusion vulnerability in admin/admin_topic_action_logging.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 phpbb_root_path parameter. | 
    
    
    
        | 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. | 
    
    
    
        | SQL injection vulnerability in guestbook.php in Advanced Guestbook 2.4 for phpBB allows remote attackers to execute arbitrary SQl commands via the entry parameter. | 
    
    
    
        | 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." | 
    
    
    
        | Cross-site scripting (XSS) vulnerability in guestbook.php in Advanced Guestbook 2.4 for phpBB allows remote attackers to inject arbitrary web script or HTML via the entry parameter.  NOTE: this issue might be resultant from SQL injection. | 
    
    
    
        | 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. | 
    
    
    
        | 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 phpbb_root_path parameter.  NOTE: CVE and the vendor dispute this vulnerability because $phpbb_root_path is defined before use | 
    
    
    
        | Cross-site scripting (XSS) vulnerability in calendar_scheduler.php in the Topic Calendar 1.0.1 module for phpBB allows remote attackers to inject arbitrary web script or HTML via the start parameter. | 
    
    
    
        | SQL injection vulnerability in charts.php in the Chart mod for phpBB allows remote attackers to execute arbitrary SQL commands via the id parameter. | 
    
    
    
        | 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. | 
    
    
    
        | phpBB 2.0.11, and possibly other versions, with remote avatars and avatar uploading enabled, allows local users to read arbitrary files by providing both a local and remote location for an avatar, then modifying the "Upload Avatar from a URL:" field to reference the target file. | 
    
    
    
        | SQL injection vulnerability in phpBB 2 before 2.0.18 allows remote attackers to execute arbitrary SQL commands via the topic type. | 
    
    
    
        | phpBB 2.0.8a and earlier trusts the IP address that is in the X-Forwarded-For in the HTTP header, which allows remote attackers to spoof IP addresses. | 
    
    
    
        | Cross-site scripting (XSS) vulnerability in phpBB 2.0.16 allows remote attackers to inject arbitrary web script or HTML via nested [url] tags. | 
    
    
    
        | The gen_rand_string 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 scripting (XSS) vulnerability in phpBB 2.0.6d and earlier allows remote attackers to inject arbitrary web script or HTML via the (1) postdays parameter to viewtopic.php or (2) topicdays parameter to viewforum.php. |
