VCID-5qj8-vuec-h3fg
Aliases: CVE-2018-1283 |
When mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications. The severity is set to Moderate because "SessionEnv on" is not a default nor common configuration, it should be considered more severe when this is the case though, because of the possible remote exploitation. |

A limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malfomed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed. We have taken this opportunity to also remove request data from many other in-built error messages. Note however this issue did not affect them directly and their output was already escaped to prevent cross-site scripting attacks. |

HTTP_PROXY is a well-defined environment variable in a CGI process, which collided with a number of libraries which failed to avoid colliding with this CGI namespace. A mitigation is provided for the httpd CGI environment to avoid populating the "HTTP_PROXY" variable from a "Proxy:" header, which has never been registered by IANA. This workaround and patch are documented in the ASF Advisory at asf-httpoxy-response.txt and incorporated in the 2.4.25 and 2.2.32 releases. Note: This is not assigned an httpd severity, as it is a defect in other software which overloaded well-established CGI environment variables, and does not reflect an error in HTTP server software. |

This module continued to compress large files until compression was complete, even if the network connection that requested the content was closed before compression completed. This would cause mod_deflate to consume large amounts of CPU if mod_deflate was enabled for a large file. |

Aliases: CVE-2016-8743 |
Apache HTTP Server, prior to release 2.4.25 (and 2.2.32), accepted a broad pattern of unusual whitespace patterns from the user-agent, including bare CR, FF, VTAB in parsing the request line and request header lines, as well as HTAB in parsing the request line. Any bare CR present in request lines was treated as whitespace and remained in the request field member "the_request", while a bare CR in the request header field name would be honored as whitespace, and a bare CR in the request header field value was retained the input headers array. Implied additional whitespace was accepted in the request line and prior to the ':' delimiter of any request header lines. RFC7230 Section 3.5 calls out some of these whitespace exceptions, and section 3.2.3 eliminated and clarified the role of implied whitespace in the grammer of this specification. Section 3.1.1 requires exactly one single SP between the method and request-target, and between the request-target and HTTP-version, followed immediately by a CRLF sequence. None of these fields permit any (unencoded) CTL character whatsoever. Section 3.2.4 explicitly disallowed any whitespace from the request header field prior to the ':' character, while Section 3.2 disallows all CTL characters in the request header line other than the HTAB character as whitespace. These defects represent a security concern when httpd is participating in any chain of proxies or interacting with back-end application servers, either through mod_proxy or using conventional CGI mechanisms. In each case where one agent accepts such CTL characters and does not treat them as whitespace, there is the possiblity in a proxy chain of generating two responses from a server behind the uncautious proxy agent. In a sequence of two requests, this results in request A to the first proxy being interpreted as requests A + A' by the backend server, and if requests A and B were submitted to the first proxy in a keepalive connection, the proxy may interpret response A' as the response to request B, polluting the cache or potentially serving the A' content to a different downstream user-agent. These defects are addressed with the release of Apache HTTP Server 2.4.25 and coordinated by a new directive; HttpProtocolOptions Strict which is the default behavior of 2.4.25 and later. By toggling from 'Strict' behavior to 'Unsafe' behavior, some of the restrictions may be relaxed to allow some invalid HTTP/1.1 clients to communicate with the server, but this will reintroduce the possibility of the problems described in this assessment. Note that relaxing the behavior to 'Unsafe' will still not permit raw CTLs other than HTAB (where permitted), but will allow other RFC requirements to not be enforced, such as exactly two SP characters in the request line. |

mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all. |

A design error in the "ap_some_auth_required" function renders the API unusuable in httpd 2.4.x. In particular the API is documented to answering if the request required authentication but only answers if there are Require lines in the applicable configuration. Since 2.4.x Require lines are used for authorization as well and can appear in configurations even when no authentication is required and the request is entirely unrestricted. This could lead to modules using this API to allow access when they should otherwise not do so. API users should use the new ap_some_authn_required API added in 2.4.16 instead. |

There was no vulnerability on earlier versions, as proxy pools were not yet introduced. The simplest workaround is to globally configure: SetEnv proxy-nokeepalive 1 |
CVE-2010-2791
|
| VCID-m7yt-8eaj-wbes | suexec in Apache HTTP Server (httpd) 2.2.3 uses a partial comparison for verifying whether the current directory is within the document root, which might allow local users to perform unauthorized operations on incorrect directories, as demonstrated using "html_backup" and "htmleditor" under an "html" directory. NOTE: the researcher, who is reliable, claims that the vendor disputes the issue because "the attacks described rely on an insecure server configuration" in which the user "has write access to the document root." |
CVE-2007-1742
|
| VCID-nr4a-3nb8-23fx | Multiple race conditions in suexec in Apache HTTP Server (httpd) 2.2.3 between directory and file validation, and their usage, allow local users to gain privileges and execute arbitrary code by renaming directories or performing symlink attacks. NOTE: the researcher, who is reliable, claims that the vendor disputes the issue because "the attacks described rely on an insecure server configuration" in which the user "has write access to the document root." |
CVE-2007-1741
|
| VCID-q44z-7zkg-8yf9 | The Apache HTTP server did not verify that a process was an Apache child process before sending it signals. A local attacker with the ability to run scripts on the HTTP server could manipulate the scoreboard and cause arbitrary processes to be terminated which could lead to a denial of service. |
CVE-2007-3304
|
| VCID-q9d7-7krq-mfdq | A flaw was found in the mod_status module. On sites where the server-status page is publicly accessible and ExtendedStatus is enabled this could lead to a cross-site scripting attack. Note that the server-status page is not enabled by default and it is best practice to not make this publicly available. |
CVE-2006-5752
|
| VCID-ra8d-gxqs-cbgy | A flaw was found in the mod_proxy_balancer module. On sites where mod_proxy_balancer is enabled, a cross-site scripting attack against an authorized user is possible. |
CVE-2007-6421
|
| VCID-uv7q-n8wy-xqbm | Apache HTTP Server 2.0.x and 2.2.x does not sanitize the HTTP Method specifier header from an HTTP request when it is reflected back in a "413 Request Entity Too Large" error message, which might allow cross-site scripting (XSS) style attacks using web client components that can send arbitrary headers in requests, as demonstrated via an HTTP request containing an invalid Content-length value, a similar issue to CVE-2006-3918. |
