libpurple OTR information leakage

census ID:census-2012-0001
CVE ID:CVE-2012-1257
Affected Products:libpurple (all versions), libpurple clients with DBUS support (incl. all versions of pidgin), pidgin-otr (all versions)
Class:Information Exposure (CWE-200), Privacy Violation (CWE-359), Information Exposure Through Sent Data (CWE-201)
Remote:No
Discovered by:Dimitris Glynos

libpurple-based applications broadcast the plaintext of OTR (off-the-record) conversations over DBUS. This makes the plaintext available to other (possibly unrelated) applications executing under the same user. Also, due to a design flaw in libpurple, the user’s choice of not logging OTR plaintext on Pidgin is not communicated over to the third party applications listening on DBUS. This may lead to unintentional (on disk) logging of private messages.

Netvolution referer header SQL injection vulnerability

CENSUS ID:CENSUS-2011-0001
CVE ID:CVE-2011-3340
Affected Products:Netvolution v2.5.8 (ASP). Other versions may also be vulnerable.
Class:Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’) (CWE-89)
Remote:Yes
Discovered by:Patroklos Argyroudis
Researched and Exploited by:Dimitris Glynos

Netvolution v2.5.8 is vulnerable to a blind SQL injection attack in the HTTP “referer” header. A malicious user may utilize this vulnerability to modify content on the vulnerable website, inject malicious javascript code to a visitor’s browser, collect CMS usernames and plaintext passwords and, in some cases, execute commands on the system hosting the database server. This is a critical vulnerability since it does not require authentication and its exploitation may go undetected.
