tomcat: Multiple weaknesses in HTTP DIGEST authentication

The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not check qop values, which might allow remote attackers to bypass intended integrity-protection requirements via a qop=auth value, a different vulnerability than CVE-2011-1184.

struts: improper access restrictions to collections such as session and request

Apache Struts 2.3.1.2 and earlier, 2.3.19-2.3.23, provides interfaces that do not properly restrict access to collections such as the session and request collections, which might allow remote attackers to modify run-time data values via a crafted parameter to an application that implements an affected interface, as demonstrated by the SessionAware, RequestAware, ApplicationAware, ServletRequestAware, ServletResponseAware, and ParameterAware interfaces. NOTE: the vendor disputes the significance of this report because of an "easy work-around in existing apps by configuring the interceptor."

apache-geronimo: hash table collisions CPU usage DoS

Apache Geronimo 2.2.1 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. NOTE: this might overlap CVE-2011-4461.

ActiveMQ: flaw within failover mechanism when handling openwire requests can lead to DoS

Apache ActiveMQ before 5.6.0 allows remote attackers to cause a denial of service (file-descriptor exhaustion and broker crash or hang) by sending many openwire failover:tcp:// connection requests.

tomcat: hash table collisions CPU usage DoS (oCERT-2011-003)

Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.

httpd: SetEnvIf resource exhaustion

The ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, does not restrict the size of values of environment variables, which allows local users to cause a denial of service (memory consumption or NULL pointer dereference) via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, related to (1) the "len +=" statement and (2) the apr_pcalloc function call, a different vulnerability than CVE-2011-3607.

httpd: uri scheme bypass of the reverse proxy vulnerability CVE-2011-3368 fix

The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21, when the Revision 1179239 patch is in place, does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an @ (at sign) character and a : (colon) character in invalid positions. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3368.

httpd: http 0.9 request bypass of the reverse proxy vulnerability CVE-2011-3368 fix

The mod_proxy module in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x before 2.2.18, when the Revision 1179239 patch is in place, does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers by using the HTTP/0.9 protocol with a malformed URI containing an initial @ (at sign) character. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3368.

qpid-cpp: cluster authentication ignores cluster-* settings

Apache Qpid 0.12 does not properly verify credentials during the joining of a cluster, which allows remote attackers to obtain access to the messaging functionality and job functionality of a cluster by leveraging knowledge of a cluster-username.

httpd: ap_pregsub Integer overflow to buffer overflow

Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, allows local users to gain privileges via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, leading to a heap-based buffer overflow.

tomcat: Privilege escalation via the Manager application

org/apache/catalina/core/DefaultInstanceManager.java in Apache Tomcat 7.x before 7.0.22 does not properly restrict ContainerServlets in the Manager application, which allows local users to gain privileges by using an untrusted web application to access the Manager application's functionality.

tomcat: information disclosure due to improper response and request object recycling

Apache Tomcat 6.0.30 through 6.0.33 and 7.x before 7.0.22 does not properly perform certain caching and recycling operations involving request objects, which allows remote attackers to obtain unintended read access to IP address and HTTP header information in opportunistic circumstances by reading TCP data.

httpd: reverse web proxy vulnerability

The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an initial @ (at sign) character.

httpd: mod_proxy_ajp remote temporary DoS

The mod_proxy_ajp module in the Apache HTTP Server before 2.2.21, when used with mod_proxy_balancer in certain configurations, allows remote attackers to cause a denial of service (temporary "error state" in the backend server) via a malformed HTTP request.

httpd: multiple ranges DoS

The byterange filter in the Apache HTTP Server 1.3.x, 2.0.x through 2.0.64, and 2.2.x through 2.2.19 allows remote attackers to cause a denial of service (memory and CPU consumption) via a Range header that expresses multiple overlapping ranges, as exploited in the wild in August 2011, a different vulnerability than CVE-2007-0086.

tomcat: authentication bypass and information disclosure

Certain AJP protocol connector implementations in Apache Tomcat 7.0.0 through 7.0.20, 6.0.0 through 6.0.33, 5.5.0 through 5.5.33, and possibly other versions allow remote attackers to spoof AJP requests, bypass authentication, and obtain sensitive information by causing the connector to interpret a request body as a new request.

jakarta-commons-daemon: jsvc does not drop capabilities allowing access to files and directories owned by the superuser

native/unix/native/jsvc-unix.c in jsvc in the Daemon component 1.0.3 through 1.0.6 in Apache Commons, as used in Apache Tomcat 5.5.32 through 5.5.33, 6.0.30 through 6.0.32, and 7.0.x before 7.0.20 on Linux, does not drop capabilities, which allows remote attackers to bypass read permissions for files via a request to an application.

Cross-site scripting (XSS) vulnerability in Apache Wicket 1.4.x before 1.4.18, when setAutomaticMultiWindowSupport is enabled, allows remote attackers to inject arbitrary web script or HTML via unspecified parameters.

SQL injection vulnerability in mysql/mysql-auth.pl in the mod_authnz_external module 3.2.5 and earlier for the Apache HTTP Server allows remote attackers to execute arbitrary SQL commands via the user field.

tomcat: security manager restrictions bypass

Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.19, when sendfile is enabled for the HTTP APR or HTTP NIO connector, does not validate certain request attributes, which allows local users to bypass intended file access restrictions or cause a denial of service (infinite loop or JVM crash) by leveraging an untrusted web application.
