DescriptionCVE.org

QloApps through 1.7.0, fixed in commit 64e9722, contains a weak cryptographic algorithm vulnerability that allows attackers to compromise user credentials by exploiting the use of MD5 for password hashing in the Tools::encrypt() function within classes/Tools.php, which concatenates a static cookie key with the supplied password. Attackers can perform offline brute-force attacks against the MD5 hashes, with the risk compounded by auto-generated 8-character passwords assigned during guest-to-customer account conversion in classes/Customer.php, making credential recovery trivial.

AnalysisAI

Weak password hashing in QloApps through 1.7.0 enables credential compromise because Tools::encrypt() in classes/Tools.php hashes passwords with unsalted MD5 concatenated with a static cookie key, allowing offline brute-force recovery of customer and employee credentials. The risk is amplified by an 8-character auto-generated password used during guest-to-customer conversion in classes/Customer.php, making cracked hashes practically trivial. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to first obtain QloApps password hashes from the database (via prior SQLi, backup exposure, host compromise, or insider access) and to know or recover the site-specific static cookie key concatenated by Tools::encrypt() in classes/Tools.php; without the hash material the MD5 weakness alone is not directly reachable over the network despite the CVSS AV:N rating, which is reflected in AC:H. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment CVSS 4.0 scores this 8.2 (High) with vector AV:N/AC:H/PR:N/UI:N and VC:H/VI:N/VA:N - confidentiality-only impact reflecting that the bug yields credentials rather than direct code execution, and AC:H acknowledges the attacker must first obtain the password database (e.g., via SQLi, backup leak, or insider access) before the MD5 weakness becomes useful. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who obtains a copy of a QloApps database - for example via a separate SQL injection, a leaked backup, or insider access - extracts the passwd columns from ps_customer and ps_employee and runs hashcat against the MD5(cookie_key||password) construction using a leaked or recovered cookie key. Because guest-converted accounts use only 8-character auto-generated passwords, exhaustive search over that keyspace recovers cleartext credentials in minutes on commodity GPUs, which the attacker then replays against the storefront and admin panel, and likely against other sites where customers reused the password. …
Remediation Upstream fix available (commit 64e9722); a released patched version is not independently confirmed in the provided data, so operators should pull commit 64e9722e7e6a8fda77dd53964d988fb6b5c3d174 from the Qloapps/QloApps repository or the next tagged release after 1.7.0 that includes PR #1689. … Detailed patch versions, workarounds, and compensating controls in full report.
