CVE-2011-2483: crypt_blowfish before 1.1, as used in PHP before 5.3.7 on certain platforms, PostgreSQL before 8.4.9, and other products, does not properly…
Noroxi assessment
Priority: Monitor (action score 21/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 4.9% (FIRST EPSS); higher than 92.3% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: libxcrypt (Debian:12) 1:2.4-1.1; php5 (Debian:5.0) 5.2.6.dfsg.1-1+lenny14; postgresql-8.3 (Debian:5.0) 8.3.16-0lenny1.
Low priority for now. Upgrade to libxcrypt (Debian:12) 1:2.4-1.1; php5 (Debian:5.0) 5.2.6.dfsg.1-1+lenny14; postgresql-8.3 (Debian:5.0) 8.3.16-0lenny1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
crypt_blowfish before 1.1, as used in PHP before 5.3.7 on certain platforms, PostgreSQL before 8.4.9, and other products, does not properly handle 8-bit characters, which makes it easier for context-dependent attackers to determine a cleartext password by leveraging knowledge of a password hash.
