Vulnerabilidades

The fmtstr function in crypto/bio/b_print.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g improperly calculates string lengths, which allows remote attackers to cause a denial of service (overflow and out-of-bounds read) or possibly have unspecified other impact via a long string, as demonstrated by a large…

The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a…

Stack-based buffer overflow in the normify function in the rlm_pap module (modules/rlm_pap/rlm_pap.c) in FreeRADIUS 2.x, possibly 2.2.3 and earlier, and 3.x, possibly 3.0.1 and earlier, might allow attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long password hash, as…

Multiple format string vulnerabilities in Yet Another Radius Daemon (YARD RADIUS) 1.1.2 allow context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via format string specifiers in a request in the (1) log_msg function in log.c or (2) version or (3) build_version function…

Buffer overflow in the radius_get_vendor_attr function in the Radius extension before 1.2.7 for PHP allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large Vendor Specific Attributes (VSA) length value.

modules/rlm_unix/rlm_unix.c in FreeRADIUS before 2.2.0, when unix mode is enabled for user authentication, does not properly check the password expiration in /etc/shadow, which allows remote authenticated users to authenticate using an expired password.

Stack-based buffer overflow in the cbtls_verify function in FreeRADIUS 2.1.10 through 2.1.12, when using TLS-based EAP methods, allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via a long "not after" timestamp in a client certificate.

WinRadius Server 2009 allows remote attackers to cause a denial of service (crash) via a long password in an Access-Request packet.

The ocsp_check function in rlm_eap_tls.c in FreeRADIUS 2.1.11, when OCSP is enabled, does not properly parse replies from OCSP responders, which allows remote attackers to bypass authentication by using the EAP-TLS protocol with a revoked X.509 client certificate.

Multiple cross-site scripting (XSS) vulnerabilities in Radius Manager 3.8.0 allow remote authenticated administrators to inject arbitrary web script or HTML via the (1) name or (2) descr parameter in an (a) update_usergroup or a (b) store_nas action to admin.php.

The wait_for_child_to_die function in main/event.c in FreeRADIUS 2.1.x before 2.1.10, in certain circumstances involving long-term database outages, does not properly handle long queue times for requests, which allows remote attackers to cause a denial of service (daemon crash) by sending many requests.

The fr_dhcp_decode function in lib/dhcp.c in FreeRADIUS 2.1.9, in certain non-default builds, does not properly handle the DHCP Relay Agent Information option, which allows remote attackers to cause a denial of service (infinite loop and daemon outage) via a packet that has more than one sub-option. NOTE: some of…

Cross-site scripting (XSS) vulnerability in daloradius-users/login.php in daloRADIUS 0.9-8 and earlier allows remote attackers to inject arbitrary web script or HTML via the error parameter.

The rad_decode function in FreeRADIUS before 1.1.8 allows remote attackers to cause a denial of service (radiusd crash) via zero-length Tunnel-Password attributes, as demonstrated by a certain module in VulnDisco Pack Professional 7.6 through 8.11. NOTE: this is a regression error related to CVE-2003-0967.

Multiple SQL injection vulnerabilities in TekRADIUS 3.0 allow context-dependent attackers to execute arbitrary SQL commands via (1) the GUI client, as demonstrated by input to the Browse Users text box in the Users tab; or (2) the command-line client, as demonstrated by a certain trcli -r command.

TekRADIUS 3.0 uses BUILTIN\Users:R permissions for the TekRADIUS.ini file, which allows local users to obtain obfuscated database credentials by reading this file.

The default configuration of TekRADIUS 3.0 uses the sa account to communicate with Microsoft SQL Server, which makes it easier for remote attackers to obtain privileged access to the database and the underlying Windows operating system.

The web server in IEA Software RadiusNT and RadiusX 5.1.38 and other versions before 5.1.44, Emerald 5.0.49 and other versions before 5.0.52, Air Marshal 2.0.4 and other versions before 2.0.8, and Radius test client (aka Radlogin) 4.0.20 and earlier, allows remote attackers to cause a denial of service (crash) via an…

freeradius-dialupadmin in freeradius 2.0.4 allows local users to overwrite arbitrary files via a symlink attack on temporary files in (1) backup_radacct, (2) clean_radacct, (3) monthly_tot_stats, (4) tot_stats, and (5) truncate_radacct.

ezRADIUS 0.1 stores sensitive information under the web root with insufficient access control, which allows remote attackers to obtain credentials via a direct request for (1) config.ini or (2) database.ini. NOTE: some of these details are obtained from third party information.

Open System Consultants (OSC) Radiator before 4.0 allows remote attackers to cause a denial of service (daemon crash) via malformed RADIUS requests, as demonstrated by packets sent by nmap.

Memory leak in freeRADIUS 1.1.5 and earlier allows remote attackers to cause a denial of service (memory consumption) via a large number of EAP-TTLS tunnel connections using malformed Diameter format attributes, which causes the authentication request to be rejected but does not reclaim VALUE_PAIR data structures.

Buffer overflow in the SMB_Connect_Server function in FreeRadius 1.1.3 and earlier allows attackers to execute arbitrary code related to the server desthost field of an SMB_Handle_Type instance. NOTE: the impact of this issue has been disputed by a reliable third party and the vendor, who states that exploitation is…

Format string vulnerability in the sqllog function in the SQL accounting code for radiusd in GNU Radius 1.2 and 1.3 allows remote attackers to execute arbitrary code via unknown vectors.

Unspecified vulnerability in FreeRADIUS 1.0.0 up to 1.1.0 allows remote attackers to bypass authentication or cause a denial of service (server crash) via "Insufficient input validation" in the EAP-MSCHAPv2 state machine module.
